Evidence for Core Collapse in the Type Ib/c SN 1999ex

Mario Hamuy, Maximilian Stritzinger, M. M. Phillips +3

We present optical and infrared spectra of SN 1999ex that reveal a clear example of an intermediate Type Ib/c case. This suggests a continuous spectroscopic sequence between Type I…

The Evolution of the Global Stellar Mass Density at 0 < z < 3

Mark Dickinson, Casey Papovich, Henry C. Ferguson +1

The build-up of stellar mass in galaxies is the consequence of their past star formation and merging histories. Here we report measurements of rest-frame optical light and calculat…

Spectrophotometry with a transmission grating for detecting faint occultations

M. A. Kenworthy, P. M. Hinz

High-precision spectrophotometry is highly desirable in detecting and characterizing close-in extrasolar planets to learn about their makeup and temperature. For such a goal, a mod…

Representations of Affine Quantum Function Algebras

Bharath Narayanan

Let be a symmetrizable generalized Cartan Matrix, and an indeterminate. ${\fg}(C)$ is the Kac-Moody Lie algebra and $U=U_q({\fg}(C))$ the associated quantum enveloping alge…

The Role of the Roper in QCD

Silas R. Beane, Ubirajara van Kolck

We show that existing data suggest a simple scenario in which the nucleon, and the Delta and Roper resonances act as chiral partners in a reducible representation of the full QCD c…

Near-Infrared Observations of Powerful High-Redshift Radio Galaxies: 4C 40.36 and 4C 39.37

E. Egami, L. Armus, G. Neugebauer +4

We present near-infrared imaging and spectroscopic observations of two FR II high-redshift radio galaxies (HzRGs), 4C 40.36 (z=2.3) and 4C 39.37 (z=3.2), obtained with the Hubble,…

The [FeII]1.644micron emission in M82 and NGC253: Is it a measure of the supernova rate?

Almudena Alonso-Herrero, George H. Rieke, Marcia J. Rieke +1

We present HST/NICMOS [FeII]1.644micron, Pa-alpha (1.87micron) and continuum images of the starburst galaxies M82 and NGC253 at an unprecedented spatial resolution. In both galaxie…

Estimating Star Formation Rates from Infrared and Radio Luminosities: The Origin of the Radio-Infrared Correlation

Eric F. Bell

I have assembled a diverse sample of galaxies from the literature with far-ultraviolet (FUV), optical, infrared (IR) and radio luminosities to explore the calibration of radio-deri…

The overdensities of galaxy environments as a function of luminosity and color

David W. Hogg, Michael R. Blanton, Daniel J. Eisenstein +9

We study the mean environments of galaxies in the Sloan Digital Sky Survey as a function of rest-frame luminosity and color. Overdensities in galaxy number are estimated in $8 h^{-…
