REQUIEM survey. I. Ly{alpha} halos around QSOs
The discovery of quasars a few hundred megayears after the Big Bang represents a major challenge to our understanding of black holes as well as galaxy formation and evolution.... -
Completed KMOS^3D^ survey NIR obs.
We present the completed KMOS^3D^ survey, an integral field spectroscopic survey of 739 log(M_/M{sun})>9 galaxies at 0.6<z<2.7 using the K-band Multi Object... -
Opt. follow-up of galaxies within S190814bv region
On 2019 August 14 the Laser Interferometer Gravitational Wave Observatory (LIGO) and the Virgo gravitational wave interferometer announced the detection of a binary merger,... -
Spectra & HST obs. of gal. in 1ES1553+113 field
The relationship between galaxies and the state/chemical enrichment of the warm-hot intergalactic medium (WHIM) expected to dominate the baryon budget at low-z provides... -
ULXs with multiepoch Spitzer/IRAC obs.
We present a mid-infrared (IR) sample study of nearby ultraluminous X-ray sources (ULXs) using multiepoch observations with the Infrared Array Camera (IRAC) on the Spitzer Space... -
SPIRITS catalog of IR long period variables
We present a catalog of 417 luminous infrared variable stars with periods exceeding 250 days. These were identified in 20 nearby galaxies by the ongoing SPitzer InfraRed... -
Kepler rapid rotators and Ks-band excesses
Tens of thousands of rotation periods have been measured in the Kepler fields, including a substantial fraction of rapid rotators. We use Gaia parallaxes to distinguish... -
Large-scale structure of M31 halo. II. PAndAS
The Pan-Andromeda Archaeological Survey is a survey of >400deg^2^ centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive panorama... -
Spitzer observations of Y and T dwarfs
Y dwarfs provide a unique opportunity to study free-floating objects with masses <30M_Jup_ and atmospheric temperatures approaching those of known Jupiter-like exoplanets.... -
Variability of RSGs in M31 from the iPTF survey
Most massive stars end their lives as red supergiants (RSGs), a short-lived evolutionary phase when they are known to pulsate with varying amplitudes. The RSG period-luminosity... -
Lyman break galaxies at z~6-9 from HFF
We construct z~6-7, 8, and 9 faint Lyman break galaxy samples (334, 61, and 37 galaxies, respectively) with accurate size measurements with the software glafic from the complete... -
Galaxies probing galaxies in PRIMUS. I.
The spectroscopy of background QSO sightlines passing close to foreground galaxies is a potent technique for studying the circumgalactic medium (CGM). However, QSOs are... -
Variable stars in M31 and M33. V. HR diagram
We present HR diagrams for the massive star populations in M31 and M33, including several different types of emission-line stars: the confirmed luminous blue variables (LBVs),... -
Massive star cluster in LIRGs in GOALS.
We present the results of a Hubble Space Telescope ACS/HRC FUV, ACS/WFC optical study into the cluster populations of a sample of 22 Luminous Infrared Galaxies in the Great... -
Improved reddenings for 59 Galactic Cepheids
We present a new photometric method by which improved high-precision reddenings and true distance moduli can be determined to individual Galactic Cepheids once distance... -
N/O ratio of dwarf galaxies from SDSS
We examine how the cosmic environment affects the chemical evolution of galaxies in the universe by comparing the N/O ratio of dwarf galaxies in voids with that of dwarf... -
Hawaii infrared parallax program. II. Ultracool dwarfs
We present a large, uniform analysis of young (~10-150Myr) ultracool dwarfs, based on new high-precision infrared (IR) parallaxes for 68 objects. We find that low-gravity (VL-G)... -
SDSS/BOSS/TDSS CIV BAL quasars
We present results from the largest systematic investigation of broad absorption line (BAL) acceleration to date. We use spectra of 140 quasars from three Sloan Digital Sky... -
Stellar MFP for massive quiescent z<0.7 galaxies
We examine the evolution of the relation between stellar mass surface density, velocity dispersion, and half-light radius --the stellar mass fundamental plane (MFP)-- for... -
Luminous AGNs and early-type SDSS galaxies
It is not yet clear what triggers the activity of active galactic nuclei (AGNs), but galaxy merging has been suspected to be one of the main mechanisms fueling the activity....
