In the Journal Club this week I’ll discuss the latest paper by John Kormendy (http://adsabs.harvard.edu/abs/2012ApJS..198….2K) where they propose a modification in the Hubble tunning-fork diagram where the galaxies are classified morphologically. In this paper they propose to include a new category, the spheroidals, to account for all the dwarf early-type galaxies, and their position in this diagram is directly related with their formation mechanisms.

At journal club this week I will present a recent Nature paper by Charpinet et al. claiming the discovery of two very close-in planets orbiting an evolved (sdB subdwarf) star.  The planets are presumed to have survived being immersed within the star’s envelope during its red giant phase:

As there was a new paper by Jim Dale today, I’m going to review recent simulations on ionization-induced star formation, mainly:

Walch et al.: ‘Flaws in the perfect bubble’ http://arxiv.org/abs/1109.3478

Arthur et al.: ‘Radiation-magnetohydrodynamic simulations of HII regions and their associated PDRs in turbulent molecular clouds’ http://arxiv.org/abs/1101.5510

I will be presenting some highlights from the recent review article “Multiple populations in globular clusters, Lessons learned from Milky Way globular clusters”, by R. Gratton, E. Carretta, and A. Bragaglia.

http://xxx.lanl.gov/abs/1201.6526

This week, Dan Fabrycky will present some exciting new results from Kepler (see his email to academics).

In this week’s Journal Club, I’ll give a quick update on current observational constraints on the reionization history, and I’ll discuss a recent paper which combines the evolution of the UV LF at z>4 and the Lya forest data at z<6 to come up with constraints on the sources of reionization :

Kuhlen & Faucher-Giguere, 2012,  http://adsabs.harvard.edu/abs/2012arXiv1201.0757K

See you there.

At Journal Club we will discuss the following paper:

http://arxiv.org/abs/1111.2048

This week I’ll discuss how one can use Type I X-ray bursts to place constraints on the mass and radius of the underlying neutron star.  This in turn may rule out various theories regarding the equation of state of very high-density material.

I’ll briefly introduce some of the approaches used to constrain the neutron star properties using the so-called Photospheric Radius Expansion (PRE) bursts, such as those described in the following two papers:

http://arxiv.org/abs/1005.0811  (Steiner et al., 2010)

http://arxiv.org/abs/1004.4871 (Suleimanov et al., 2011)

I’ll then introduce a recently proposed method, which couples 1-dimensional numerical simulations with observations to place constraints on non-PRE outbursts:

http://arxiv.org/abs/1111.0347 (Zamfir et al., 2011)

This week, we’ll discuss the claim of a significant X-ray detection in z~6 galaxies published recently:

Treister et al., Nature in press: http://arxiv.org/abs/1106.3079

This triggered a suite of papers, which unfortunately could not confirm the initial result:
Fiore et al.: http://arxiv.org/abs/1109.4586  (see also http://arxiv.org/abs/1109.2888 for more results)
Cowie et al.: http://arxiv.org/abs/1110.3326
Willot: http://arxiv.org/abs/1110.4118

I will thus summarize the results from these papers and their implications for the growth of very early black holes.

We’ll discuss the following paper this week:

http://arxiv.org/abs/1110.4636v1

see you there!

Today we will continue from last week’s round of new postdoc introductions, featuring now the not-so-new postdocs.

Obscured Starburst Activity in High Redshift Clusters and Groups

We have used Spitzer-MIPS 24um imaging and extensive Keck  spectroscopy to identify and study the obscured star forming population in and around three clusters and three groups in the  Cl1604 supercluster at z~0.9.  We find that the average density of  24um-detected galaxies within the Cl1604 clusters is nearly twice  that of the surrounding field and that this overdensity scales with  the cluster’s dynamical state.  The 24um-bright members often appear  optically unremarkable and exhibit only moderate [OII] line emission  due to severe obscuration. Their spatial distribution suggests they are an infalling population, but an examination of their spectral properties, morphologies and optical colors indicate they are not simply analogs of the field population that have yet to be quenched.  Using stacked composite spectra, we find the 24um-detected cluster and group galaxies exhibit elevated levels of Balmer absorption compared to what is expected from normal, continuous star formation activity. A similar excess is not observed in field galaxies with equivalent infrared luminosities.  This implies a greater fraction of the detected cluster and group members are experiencing starburst activity compared to their counterparts in the field.  Using HST-ACS imaging we find that disturbed morphologies are common among the 24um-detected cluster and group members and become more prevalent in regions of higher galaxy density.  We conclude that mergers are the dominant triggering mechanism responsible for the enhanced star formation found in the Cl1604 groups, while a mix of harassment and mergers are likely driving the activity of the cluster galaxies.
