A New Constraint on the Escape Fraction in Distant Galaxies Using Gamma-ray Burst Afterglow Spectroscopy
Hsiao-Wen Chen, Jason X. Prochaska, Nickolay Y. Gnedin
We describe a new method to measure the escape fraction fesc of ionizing radiation from distant star-forming galaxies using the afterglow spectra of long-duration gamma-ray bursts…
HST and Spitzer imaging of red and blue galaxies at z~2.5: A correlation between size and star formation activity from compact quiescent galaxies to extended star forming galaxies
S. Toft, P. van Dokkum, M. Franx +13
We present HST NICMOS+ACS and Spitzer IRAC+MIPS observations of 41 galaxies at 2<z<3.5 in the FIRES MS1054 field with red and blue rest-frame optical colors. About half of the gala…
Selection Bias in Observing the Cosmological Evolution of the Mbh-sigma and Mbh-L Relationships
Tod R. Lauer, Scott Tremaine, Douglas Richstone +1
Programs to observe evolution in the Mbh-sigma or Mbh-L relations typically compare black-hole masses, Mbh, in high-redshift galaxies selected by nuclear activity to Mbh in local g…
Stellar Evolution in NGC 6791: Mass Loss on the Red Giant Branch and the Formation of Low Mass White Dwarfs
Jasonjot S. Kalirai, P. Bergeron, Brad M. S. Hansen +4
We present the first detailed study of the properties (temperatures, gravities, and masses) of the NGC 6791 white dwarf population. This unique stellar system is both one of the ol…
Looking for Giant Earths in the HD 209458 System: A Search for Transits in MOST Space-based Photometry
Bryce Croll, Jaymie M. Matthews, Jason F. Rowe +11
We have made a comprehensive transit search for exoplanets down to about 2 Earth radii in the HD 209458 system, based on nearly uninterrupted broadband optical photometry obtained…
The Stellar Mass Tully-Fisher Relation to z=1.2 from AEGIS
Susan A. Kassin, Benjamin J. Weiner, S. M. Faber +12
We combine newly measured rotation velocities, velocity dispersions, and stellar masses to construct stellar mass Tully-Fisher relations (M*TFRs) for 544 galaxies with strong emiss…
The Troublesome Broadband Evolution of GRB 061126: Does a Grey Burst Imply Grey Dust?
D. A. Perley, J. S. Bloom, N. R. Butler +18
We report on observations of a gamma-ray burst (GRB 061126) with an extremely bright (R ~ 12 mag at peak) early-time optical afterglow. The optical afterglow is already fading as a…
Tidal dissipation in rotating solar-type stars
G. I. Ogilvie, D. N. C. Lin
We calculate the excitation and dissipation of low-frequency tidal oscillations in uniformly rotating solar-type stars. For tidal frequencies smaller than twice the spin frequency,…
Constraints on Type Ib/c and GRB Progenitors
C. L. Fryer, P. A. Mazzali, J. Prochaska +14
Although there is strong support for the collapsar engine as the power source of long-duration gamma-ray bursts (GRBs), we still do not definitively know the progenitor of these ex…
A Keck Spectroscopic Survey of MS1054-03 (z=0.83): Forming the Red Sequence
Kim-Vy H. Tran, Marijn Franx, Garth D. Illingworth +4
Using a magnitude-limited, spectroscopic survey of the X-ray luminous galaxy cluster MS1054-03, we isolate 153 cluster galaxies and measure MS1054's redshift and velocity dispersio…
Creation of X-ray cavities in galaxy clusters with cosmic rays
W. G. Mathews, F. Brighenti
We describe how AGN-produced cosmic rays form large X-ray cavities and radio lobes in the hot diffuse gas in galaxy groups and clusters. Cosmic rays are assumed to be produced in a…
Circumnuclear Star Clusters in the Galaxy Merger NGC 6240, Observed with Keck Adaptive Optics and HST
L. K. Pollack, C. E. Max, G. Schneider
We discuss images of the central ~10 kpc (in projection) of the galaxy merger NGC 6240 at H and K' bands, taken with the NIRC2 narrow camera on Keck II using natural guide star ada…
Far Infrared Spitzer Observations of Elliptical Galaxies: Evidence for Extended Diffuse Dust
Pasquale Temi, Fabrizio Brighenti, William G. Mathews
Far-infrared Spitzer observations of elliptical galaxies are inconsistent with simple steady state models of dust creation in red giant stars and destruction by grain sputtering in…
