Cepheids in 3 host galaxies
This is the first of two papers reporting measurements from a program to determine the Hubble constant to ~5% precision from a refurbished distance ladder. We present new... -
Globular cluster candidates in ACS Virgo survey.
We present catalogs of globular cluster candidates for the 100 galaxies of the Advanced Camera for Surveys Virgo Cluster Survey, a large program to carry out imaging of... -
Chandra sources in 5 galaxy clusters
We present catalogs and images of optical counterparts to the Chandra-selected X-ray sources found in the fields of the five clusters RX J0152-1357, RX J0849+4452, RDCS... -
SNR 0509-67.5 surviving companion search
The community agrees that Type Ia Supernovae (SNe Ia) arise from C/O white dwarfs undergoing thermonuclear runaway. However, the full progenitor system and the process that... -
z~2-10 galaxies magnified by HFF clusters. I.
We assemble a large comprehensive sample of 2534 z~2, 3, 4, 5, 6, 7, 8, and 9 galaxies lensed by the six clusters from the Hubble Frontier Fields (HFF) program. Making use of... -
Follow-up HST obs. of a strong failed SN cand.
We present the discovery of an exceptional dimming event in a cool supergiant star in the Local Volume spiral M51. The star, dubbed M51-DS1, was found as part of a Hubble Space... -
Galaxies bulge & disk data from SHARDS & HST
We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we modeled the surface... -
HST imaging and light curves of 21 SPIRITS variables
The SPitzer InfraRed Intensive Transients Survey (SPIRITS) searched for luminous infrared (IR) transients and variables in nearly 200 nearby galaxies from 2014 to 2019, using... -
VODKA: HST discovers double SDSS-Gaia quasars
Dual supermassive black holes (SMBHs) at ~kiloparsec scales are the progenitor population of SMBH mergers and play an important role in understanding the pairing and dynamical... -
Beyond the local volume. I. HST ultracool dwarfs
Ultracool dwarf stars and brown dwarfs provide a unique probe of large-scale Galactic structure and evolution; however, until recently spectroscopic samples of sufficient size,... -
Massive star cluster in LIRGs in GOALS. II.
We present the results of a Hubble Space Telescope WFC3 near-UV and Advanced Camera for Surveys Wide Field Channel optical study into the star cluster populations of a sample of... -
HST F160W obs. of the SSA22 protocluster field
We examine possible environmental sources of the enhanced star formation and active galactic nucleus (AGN) activity in the z=3.09 SSA22 protocluster using Hubble WFC3 F160W... -
HST obs. of supernova remnants in NGC6946
We constrained the progenitor masses for 169 supernova remnants (SNRs), eight historically observed supernovae (SNe), and the black hole formation candidate in NGC 6946, finding... -
Phot. measurements of stars in & near 1E 0102.2-7219
1E 0102.2-7219 (hereafter E0102) is a young supernova remnant (SNR) in the Small Magellanic Cloud. It contains oxygen-rich SN ejecta, a possible neutron star (NS), and a small... -
HST opt. & H-band obs. of Cepheids in NGC4051
We derive a distance of D=16.6+/-0.3Mpc ({mu}=31.10+/-0.04mag) to the archetypal narrow-line Seyfert 1 galaxy NGC 4051 based on Cepheid period-luminosity relations and new... -
SED modelling of LEGA-C & HST massive gal.
We explore the connection between the kinematics, structures and stellar populations of massive galaxies at 0.6<z<1.0 using the fundamental plane (FP). Combining stellar... -
M83 X-ray binary classifications from HST
Building on recent work by Chandar+ (2020, J/ApJ/890/150), we construct X-ray luminosity functions (XLFs) for different classes of X-ray binary (XRB) donors in the nearby... -
HST opt-NIR obs. of Cepheids in NGC5584
The current tension between the direct and the early-universe measurements of the Hubble constant, H_0_, requires detailed scrutiny of all the data and methods used in the... -
RELICS 6<~z<=8 galaxies with Spitzer & HST obs.
We present constraints on the physical properties (including stellar mass, age, and star formation rate) of 207 6<=z<=8 galaxy candidates from the Reionization Lensing... -
HST opt. & H-band obs. of Cepheids in NGC4151
We derive a distance of 15.8+/-0.4Mpc to the archetypal Seyfert 1 galaxy NGC 4151 based on the near-infrared Cepheid period-luminosity relation and new Hubble Space Telescope...
