We present Herschel SPIRE and PACS maps of the Cepheus Flare clouds L1157, L1172, L1228, L1241, and L1251, observed by the Herschel Gould Belt Survey of nearby star-forming...

We present multiwavelength modeling of the afterglow from the long {gamma}-ray burst (GRB)160625B using Markov Chain Monte Carlo techniques of the afterglowpy Python package....

We present the Voigt profile (VP) models, column densities, Doppler b parameters, kinematics, and distribution of components for 422 MgII absorbers found in a survey of 249...

Using X-ray sources as sensitive probes of stellar dynamical interactions in globular clusters (GCs), we study the mass segregation and binary burning processes in {omega}Cen....

We report the discovery of a variable optical and X-ray source within the error ellipse of the previously unassociated Fermi Large Area Telescope {gamma}-ray source...

We report on NICER observations of the magnetar SGR1935+2154, covering its 2020 burst storm and long-term persistent emission evolution up to ~90days postoutburst. During the...

The degree to which the properties of protostars are affected by environment remains an open question. To investigate this, we look at the Orion A and B molecular clouds, home...

We present a study of flare rates, rotation periods, and spectroscopic activity indicators of 125 single stars within 15 parsecs and with masses between 0.1 and 0.3M_{sun}...

How stellar mass assembles within galaxies is still an open question. We present measurements of the stellar mass distribution on kiloparsec-scales for ~5500 galaxies with...

We present a systematic search for optical counterparts to 13 gravitational wave (GW) triggers involving at least one neutron star during LIGO/Virgo's third observing run (O3)....

The optical and near-infrared (OIR) polarization of starlight is typically understood to arise from the dichroic extinction of that light by dust grains whose axes are aligned...

In this paper we present a simple color-magnitude selection and obtain a large sample of 33,893 massive quiescent galaxies at intermediate redshifts (1<z<1.5). We choose...

We present the first release of a large-scale study of relatively bright (V<13.5) metal-poor stars observed with the Southern African Large Telescope (SALT), based on...

Large galaxies may contain an "atmosphere" of hot interstellar X-ray gas, and the temperature and radial density profile of this gas can be used to measure the total mass of the...

Using Jansky Very Large Array data obtained from high-resolution observations at 5.5GHz at multiple epochs in 2014 and 2019, we have detected a population of radio variables and...

The processes that shape the extended atmospheres of red supergiants, heat their chromospheres, create molecular reservoirs, drive mass loss, and create dust remain poorly...

Close white dwarf binaries consisting of a white dwarf and an A-, F-, G-, or K-type main-sequence star, henceforth close WD+AFGK binaries, are ideal systems to understand the...

We present X-SHOOTER near-IR spectroscopy of a large sample of 38 luminous (M_1450_=-29.0 to -24.4) quasars at 5.78<z<7.54, which have complementary [CII]158{mu}m...

We perform a systematic search for high-redshift (z>1.5) extreme variability quasars (EVQs) using repeat spectra from the Sixteenth Data Release of the Sloan Digital Sky...

We investigated the 65, 71, 79, 84, 119, and 163{mu}m OH doublets of 178 local (0<z<0.35) galaxies. They were observed using the Herschel/Photoconductor Array Camera and...
