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 obs. of MADCASH-1 and MADCASH-2
We present a deep Hubble Space Telescope (HST) imaging study of two dwarf galaxies in the halos of Local Volume Large Magellanic Cloud (LMC) analogs. These dwarfs were... -
HST/ACS photometry of Eridanus II
Eridanus II (Eri II) is an ultrafaint dwarf (UFD) galaxy (M_V_=-7.1) located at a distance close to the Milky Way virial radius. Early shallow color-magnitude diagrams (CMDs)... -
HST stellar photometry of Eridanus II
We present deep Hubble Space Telescope (HST) photometry of the ultra-faint dwarf galaxy EridanusII (EriII). EriII, which has an absolute magnitude of MV=-7.1, is located at a... -
HST UV/optical photometry in NGC 1978
Multiple stellar populations (MPs) with different chemical compositions are not exclusive features of old globular clusters (older than 10Gyr). Indeed, recent studies reveal... -
The Carnegie-Chicago Hubble Program IX. TRGB in M106
In the nearby galaxy NGC4258, the well-modeled orbital motion of H_2_O masers about its supermassive black hole provides the means to measure a precise geometric distance. As a... -
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... -
HST obs. & Gaia data of Hercules dwarf gal.
The ultrafaint dwarf galaxy Hercules has an extremely elongated morphology with both photometric overdensities and kinematic members at large radii, suggesting that it may be... -
Optical & FeII sources in Supernova remnant with HST
NGC6946 is a high-star-formation-rate, face-on, spiral galaxy that has hosted 10 supernovae since 1917. Not surprisingly, a large number of supernova remnants and candidates... -
CLEAR. II. SFRs of quiescent galaxies
The origin of the correlations between mass, morphology, quenched fraction, and formation history in galaxies is difficult to define, primarily due to the uncertainties in... -
Cepheids HST amplitudes in V- and H-band
The accuracy of the Hubble constant measured with extragalactic Cepheids depends on robust photometry and background estimation in the presence of stellar crowding. The... -
HST obs. of Mira variables in the SNIa host NGC1559
We present year-long, near-infrared Hubble Space Telescope (HST) WFC3 observations used to search for Mira variables in NGC 1559, the host galaxy of the Type Ia supernova (SN... -
Brightest high-z galaxies in RELICS clusters
Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a view into both the extremely distant and intrinsically faint galaxy... -
LEGUS & Ha-LEGUS obs. of NGC4449 star clusters
We present a new catalog and results for the cluster system of the starburst galaxy NGC 4449, based on multiband imaging observations taken as part of the LEGUS and... -
The ACS-AGN Catalog: AGN luminosity vs SFR
We present the Advanced Camera for Surveys Active Galactic Nuclei (ACS-AGN) Catalog, a catalog of 2585 active galactic nucleus (AGN) host galaxies that are at redshifts... -
HST/ACS observations and SFH of Antlia B
A census of the satellite population around dwarf galaxy primary hosts in environments outside the Local Group is essential to understanding {Lambda} cold dark matter galaxy...
