Joint Survey Processing II: Stellar Proper Motions in the COSMOS Field, from Hubble Space Telescope ACS and Subaru Telescope HSC Observations
Sergio B. Fajardo-Acosta, Andreas Faisst, Carl J. Grillmair +4
We analyze stellar proper motions in the COSMOS field to assess the presence of bulk motions. At bright magnitudes (G-band 18.5--20.76 AB), we use the proper motions of 1,010 stars…
Joint Survey Processing I: Compact oddballs in the COSMOS field -- low-luminosity Quasars at z > 6?
Andreas L. Faisst, Ranga Ram Chary, Sergio Fajardo-Acosta +8
The faint-end slope of the quasar luminosity function at z~6 and its implication on the role of quasars in reionizing the intergalactic medium at early times has been an outstandin…
Joint Survey Processing of LSST, Euclid and WFIRST: Enabling a broad array of astrophysics and cosmology through pixel level combinations of datasets
R. Chary, G. Brammer, P. Capak +23
Joint survey processing (JSP) is the pixel level combination of LSST, Euclid, and WFIRST datasets. By combining the high spatial resolution of the space-based datasets with deep, s…
Stellar Velocity Dispersion in Mergers: The Effects of Dust and Star Formation
Nathaniel R. Stickley, Gabriela Canalizo
We investigate the effects of stellar evolution and dust on measurements of stellar velocity dispersion in mergers of disk galaxies. -body simulations and radiative transfer ana…
Stellar Velocity Dispersion in Dissipative Galaxy Mergers with Star Formation
Nathaniel R. Stickley, Gabriela Canalizo
In order to better understand stellar dynamics in merging systems, such as NGC 6240, we examine the evolution of central stellar velocity dispersion (\sig) in dissipative galaxy me…
The Evolution of Stellar Velocity Dispersion During Dissipationless Galaxy Mergers
Nathaniel R. Stickley, Gabriela Canalizo
Using N-body simulations, we studied the detailed evolution of central stellar velocity dispersion, σ, during dissipationless binary mergers of galaxies. Stellar velocity dispersio…
