Measuring Star Formation Histories, Distances, and Metallicities with Pixel Color-Magnitude Diagrams II: Applications to Nearby Elliptical Galaxies
B. A. Cook, Charlie Conroy, Pieter van Dokkum
We present spatially-resolved measurements of star formation histories (SFHs), metallicities, and distances in three nearby elliptical galaxies and the bulge of M31 derived using t…
Measuring Star-Formation Histories, Distances, and Metallicities with Pixel Color-Magnitude Diagrams I: Model Definition and Mock Tests
B. A. Cook, Charlie Conroy, Pieter van Dokkum +1
We present a comprehensive study of the applications of the pixel color-magnitude diagram (pCMD) technique for measuring star formation histories (SFHs) and other stellar populatio…
The information content of stellar halos: Stellar population gradients and accretion histories in early-type Illustris galaxies
B. A. Cook, C. Conroy, A. Pillepich +2
Long dynamical timescales in the outskirts of galaxies preserve the information content of their accretion histories, for example in the form of stellar population gradients. We pr…
Extremely Red Quasars in BOSS
Fred Hamann, Nadia L. Zakamska, Nicholas Ross +11
Red quasars are candidate young objects in an early transition stage of massive galaxy evolution. Our team recently discovered a population of extremely red quasars (ERQs) in the B…
Stellar populations of stellar halos: Results from the Illustris simulation
B. A. Cook, C. Conroy, A. Pillepich +1
The influence of both major and minor mergers is expected to significantly affect gradients of stellar ages and metallicities in the outskirts of galaxies. Measurements of observed…
The Sloan Digital Sky Survey quasar catalog: tenth data release
Isabelle Pâris, Patrick Petitjean, Éric Aubourg +47
We present the Data Release 10 Quasar (DR10Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS obj…
Trends in Ultracool Dwarf Magnetism. II. The Inverse Correlation Between X-ray Activity and Rotation as Evidence for a Bimodal Dynamo
B. A. Cook, P. K. G. Williams, E. Berger
Observations of magnetic activity indicators in solar-type stars exhibit a relationship with rotation with an increase until a "saturation" level and a moderate decrease in activit…
Trends in Ultracool Dwarf Magnetism. I. X-Ray Suppression and Radio Enhancement
P. K. G. Williams, B. A. Cook, E. Berger
Although ultracool dwarfs (UCDs) are now known to generate and dissipate strong magnetic fields, a clear understanding of the underlying dynamo is still lacking. We have performed…
