The Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS
Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones...
The Evolution of the Number Density of Compact Galaxies
We compare the number density of compact (small size) massive galaxies at low and high redshift using our Padova Millennium Galaxy and Group Catalogue (PM2GC)...
The Evolving Interstellar Medium of Star-forming Galaxies, as Traced by Stardust
We analyze the far-infrared (FIR) properties of ~5000 star-forming galaxies at z < 4.5, drawn from the deepest, super-deblended catalogs in the GOODS-N and...
The Extended High A(V) Quasar Survey: Searching for Dusty Absorbers toward Mid-infrared-selected Quasars
We present the results of a new spectroscopic survey for dusty intervening absorption systems, particularly damped Lyα absorbers (DLAs), toward reddened quasars...
We estimate the dust extinction laws in two intermediate-redshift galaxies. The dust in the lens galaxy of LBQS 1009-0252, which has an estimated lens redshift...
The Extreme CNO-enhanced Composition of the Primitive Iron-poor Dwarf Star J0815+4729
We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high...

We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high...
The Fast X-Ray Transient XRT 210423 and Its Host Galaxy
Fast X-ray Transients (FXTs) are X-ray flares with durations ranging from a few hundred seconds to a few hours. Possible origins include the tidal disruption of...
