week 6 minute papers

Hi Andrew,

Here is a summary of the week 6 minute papers. There were a lot of comments on being interested, scared, or both about asteroid impacts. These quotes summarize the papers pretty well:

"both super interesting and extremely terrifying"
"chixalub crater and its effects was one of the most interesting things we have discussed"

and one person said it was

"one of the scariest, most depressing classes yet"

Here is a tally of key ideas that came up:


lecture comments:

liked that you brought in meteorites  1111
interesting/fascinating/
entertaining 11111111
interesting/frightening 11111
threat of asteroid impact scary/alarming /depressing   11111111
more relatable, liked talking about Earth 111

learned about/ interested in/ thought was cool..
  
dinosaur extinction 111
   grad student discovering crater 11
evidence showing location of crater 1111

surprised by...

  impact a 10 km asteroid impact can have 1111111111

questions:

could humans survive impact? 111
what are methods for avoiding asteroid impact? 111

The Merger Environment of the Wide Agle Tail Hosting Cluster A562

Author:  Douglass, Blaton, et. al.

 Date Written: December 20, 2011

 Title: The Merger Environment of the Wide Agle Tail Hosting Cluster A562

 Subject Area: Galaxies, Active galaxies, clusters, A562 galaxy, intracluster medium, galaxies in X-rays

 Source Website:

---Notes---

physical environment studied: galaxy cluster
units: cgs and mks

WAT's are high power raadio sources generally associated with the bright central galaxy at or enar the center of its host cluster.


a562 is a galaxy cluster.

CIAO was used for data reduction

WAT radio sources

VLA radio data in 1.4 and 8.4 GHz range


Flux calibrations were done. What does '3c48 ' was 'use as a flux calibrator' mean?

Optical data from Perkins and the PRISM instrument was used.

3.

Adaptively smoothe? Background was subtracted using an observation specifc exposure map.
How was exposure subtracted?

 ---Summary---

Results: constrained interal desntiy of jets and plasma flow velocity with the lobes of the Wide Angle Tail (WAT) soruce


---
figure 3, the X-ray and radio data does not seem related to each other


3. 1

ram pressure?


3.2

the cluster was fit with a beta 2d model in Sherpa4.2

Figure 4: what does it mean by SW? lower left? Shows surface brightness of two 65 degree wedges in image a, with surface brightness as a function of semi-major axis. This is semi major axis of a galaxy, as they are rotating within the cluster? I don't see an excess of brighness in the sW of the image


4: spectral analysis

Fit spectrum to ellipticall region centeredd on AGN with e=0.27 PA (position angle) = 60 degrees (?) Model was fit with APEC in XSPEC!

Spectral fit was done of the entire cluster and sections of the cluster broken up into ellipses with at least 1000 source counts

Lx- T plot?

--there is a lot of possible conclusions

-bolometric luminosity- total luminosity of all EM waves

Figure 9 , how is mass determined from spectra?

Does htis give 3-d information of X-ray surface brightness?  a
routine that deprojects the X-ray surface brightness (see Blanton
et al. 2009) was used to give the emissivity as a function of
radius.

From wikipedia (Radio Galaxy), this is a common appearance of a radio galaxy, in this case 3C98.



















So the line bisecting the WAT is perp. to the lobes I would think.


How is this conclusion made?
'''
A surface brightness profile was
extracted from a wedge of 30

due east of the cluster center
confirming the apparent edge (Figure 10). Such a feature is
likely an indication of a merger shock created by an infalling
subcluster from the east.

'''


Dont see the excess of emission in lower left of figure 4.

What is ICM flow velocity?

Many references to previous papers


Summary-


The galaxy cluster a562, which contains the merger-bent, WAT source 0647+693, was studied.
 - X-ray images from Chandra showed relatively constant Temp as a function of radius, which indiates the absence of an active cooling flow.
-Surface brightness distrubion shows an elongation of the line which bisects the WAT, which is consistent with an ongoing merger ocuring parllel ot the line.
- 2-d temperature map shows a hot region just 'east' of the AGN, which likely is caused by merger induced shock heating.
- cluster image shows excess emission between the WAT lobes, which is likely gas displaced during an interaction.
-spectral analysis shows there is a high abundance of gas.
-time since core displacement
-Synchrotron lifetime
-combination of observational data with common merger values gives constraints on internal density of jets and plasma flow velocities within the lobes of the WAT.

 http://www.cv.nrao.edu/~awootten/astrophysics.html
wiki


 here is a postdoc position (copyied in case web loses url)
http://www.pha.jhu.edu/~neufeld/postdoc.html



Postdoctoral position in Molecular Astrophysics
(text from AAS job register with additional details at the bottom)

AAS Jobs register No. 27091


Position/Title: Postdoctoral position in Molecular Astrophysics
Institution: The Johns Hopkins University


The closing date for receipt of applications: 01/07/2011

Job Description:
Applications are invited for a postdoctoral position in molecular astrophysics in the Department of Physics and Astronomy at the Johns Hopkins University (http://physics-astronomy.jhu.edu). The successful applicant will work with Prof. David Neufeld on the analysis and interpretation of data obtained in Guaranteed Time and Open Time programs of the Herschel Space Observatory.

The starting date for this position is flexible, but could be as early as spring or as late as fall 2011. The appointment would be renewed annually, and is intended to extend for two or three years.

Applications submitted electronically through http://academicjobsonline.org/ajo/jobs/606 by Jan 7, 2011 will be given full consideration. Applicants should provide CV, publication list, statement of research interests and arrange for three letters of recommendation. JHU is an affirmative action/equal opportunity employer, and welcomes applications from women and members of underrepresented groups.

Please direct e-mail inquiries to David Neufeld (neufeld@pha.jhu.edu)

Included Benefits:
The successful candidate will officially have the rank of assistant research scientist, a position at JHU that carries full benefits, including health insurance.

Additional details:

The successful candidate will work primarily on one or more of those observational programs of the Herschel Space Observatory listed below.  Abstracts for the various Key Programs referred to below can be viewed here, and some recent results from these programs appear in an A&A special issue devoted to first results from Herschel/HIFI. The candidate could choose which topics to emphasize, based upon his or her interests and experience.

PRISMAS GTKP (Guaranteed time Key Program)

Here, our effort at JHU is centered on the chemistry of oxygen and halogen-bearing molecules in diffuse foreground clouds along sight-lines to strong continuum sources.  Molecules targeted in this program include H2O, HF, OH+, H2O+, H3O+, and HCl+.  These will be used to probe diffuse clouds of small column density and H2 fraction, to determine the cosmic ray ionization rate, and the interstellar UV radiation field.  The observations also test models for the chemistry of oxygen- chlorine- and fluorine-bearing molecules in the ISM.

A closely-related OT1 (Open time Cycle 1) proposal (PI, Neufeld) to follow up PRISMAS results has been recently approved.  The proposal text appears here.

HIFISTARS GTKP

The JHU effort is focused on the mystery of water vapor in carbon-rich AGB stars.  Recent Herschel data argue strongly against our original suggestion that such water originates from vaporization of a Kuiper belt analog (see arXiv:1012.3456 and arXiv:1012.1854)

A closely-related OT1 (Open time Cycle 1) proposal (PI, Neufeld) to follow up our HIFISTARS results has been recently approved. The proposal text appears here.

HEXOS GTKP

Our effort centers on the Orion Small Maps subprogram.  Here, we will analyse and interpret HIFI spectral line maps of roughly a dozen water vapor transitions of varying excitation in 2 x 2 arcmin maps around Orion-KL.  The goal is to elucidate the water abundances in various emission components within this complex region (the hot core, the plateau, the shocked gas traced by H2 vibrational emissions, etc)

WISH GTKP

JHU is involved in the outflows subprogram of WISH, which aims to study water in protostellar outflows.  We are responsible for analysing HIFI and PACS maps of the NGC 2071 outflow region.

A closely-related OT1 (Open time Cycle 1) proposal (PI, Brunella Nisini) to follow up WISH results on outflows has been recently approved.

WADI GTKP

JHU is involved in the shocks subprogram of WADI, which aims to study the warm and dense ISM.  We are responsible for analysing HIFI and PACS maps of the W28, W44, and 3C391 supernova remnants.

OTHER

We are also involved in two Open Time Key Programs: the HOPS (Herschel Orion Protostar survey, PI, Tom Megeath), and the Herschel Oxygen project (PI, Paul Goldsmith).

Overview of Dark Energy on Penn Staet U site

 http://hetdex.org/dark_energy/what_is_it/vacuum_energy.php

dark energy is the leading explanation for the expansion of the universe. It is a repulsive force in opposition of gravity.

 This is a pretty large discrepancy, it seems:
"
Vacuum energy has its own set of problems, though. It should be far too weak to account for the acceleration seen in the present-day universe, for example — by a factor of at least 1057 (a one followed by 57 zeroes), and perhaps as much as 10120 (a one followed by 120 zeroes). Yet it is the most complete scenario to date, so it leads the pack of dark-energy contenders.

E-mails from Breanna binder, UW grad student

Yes, Scott Anderson is my official faculty adviser, although the
majority of my research (and my thesis work) is being done with Ben
Williams. I study both AGN and X-ray binaries with X-ray and optical
data -- on the AGN side, I'm interested in low-luminosity AGN and
active intermediate-mass black holes. This year I won a Chandra
proposal to study the X-ray emission from about two dozen intermediate
mass black hole candidates, so that work will probably start next
quarter.

The bulk of my research is on XRBs in nearby galaxies. I'm not sure
how much you know about X-ray binaries, but I was a physics major too
so I came into grad school knowing very little about astronomy - so I
apologize if this is too elementary-school for you :) X-ray binaries
are systems where you have a neutron star or a black hole
gravitationally bound to a normal star. High mass XRBs have massive
stellar companions, which don't live for very long (~10 million
years), while low mass XRBs have stars more like the Sun or smaller,
and so live for billions of years.

To construct a logN-logS distribution, you basically just count up the
number of XRBs (N) brighter than a given luminosity (S). Bright
sources are rarer and younger in age than faint but numerous old
sources. By measuring the shape of the logN-logS distribution for a
galaxy, you can then say something about when the galaxy formed its
stars: for example, if the logN-logS distribution is dominated by
bright, high mass XRBs, then you know the galaxy has a significant
portion of very young stars, and so must be currently undergoing star
formation.

My thesis is taking Chandra X-ray data to study the XRBs, and
comparing it to optical Hubble Space Telescope data to study the
underlying stellar population.

I hope that wasn't too long winded! :)


----------
We find X-ray source candidates using a routine called wavdetect,
which is part of the Chandra Interactive Analysis of Observations
(CIAO) software. Once we've found a bunch of candidates, I run an IDL
program called ACIS_Extract to evaluate the source properties and the
probability that the source is real (and not some background flare or
detector noise).
