ExploreNEOs VIII: Dormant Short-Period Comets in the Near-Earth Asteroid Population
M. Mommert, A. W. Harris, M. Mueller +8
We perform a search for dormant comets, asteroidal objects of cometary origin, in the near-Earth asteroid (NEA) population based on dynamical and physical considerations. Our study…
The Evolution of the Galaxy Stellar Mass Function at z= 4-8: A Steepening Low-mass-end Slope with Increasing Redshift
Mimi Song, Steven L. Finkelstein, Matthew L. N. Ashby +16
We present galaxy stellar mass functions (GSMFs) at 4-8 from a rest-frame ultraviolet (UV) selected sample of 4500 galaxies, found via photometric redshifts over an area…
S-CANDELS: The Spitzer-Cosmic Assembly Near-Infrared Deep Extragalactic Survey. Survey Design, Photometry, and Deep IRAC Source Counts
M. L. N. Ashby, S. P. Willner, G. G. Fazio +10
The Spitzer-Cosmic Assembly Deep Near-Infrared Extragalactic Legacy Survey (S-CANDELS; PI G. Fazio) is a Cycle 8 Exploration Program designed to detect galaxies at very high redshi…
A Critical Assessment of Stellar Mass Measurement Methods
Bahram Mobasher, Tomas Dahlen, Henry C. Ferguson +34
In this paper we perform a comprehensive study of the main sources of random and systematic errors in stellar mass measurement for galaxies using their Spectral Energy Distribution…
An Increasing Stellar Baryon Fraction in Bright Galaxies at High Redshift
Steven L. Finkelstein, Mimi Song, Peter Behroozi +12
Recent observations have shown that the characteristic luminosity of the rest-frame ultraviolet (UV) luminosity function does not significantly evolve at 4 < z < 7 and is approxima…
A Spitzer/IRAC Characterization of Galactic AGB and RSG Stars
Megan Reiter, Massimo Marengo, Joseph L. Hora +1
We present new Spitzer/IRAC observations of 55 dusty Long Period Variables (LPVs, 48 AGB and 6 RSG stars) in the Galaxy that have different chemistry, variability type, and mass-lo…
