ABSTRACT UGCA 320 is a gas-rich dwarf irregular galaxy which belongs to a nearby, relatively isolated group of dwarf galaxies. Here, we combine multiband Hubble Space Telescope imaging data with deep long-slit Southern African Large Telescope/Robert Stobie Spectrograph and integral-field Very Large …

UGCA 320 is a gas-rich dwarf irregular galaxy which belongs to a nearby, relatively isolated group of dwarf galaxies. Here, we combine multi-band HST imaging data with deep long-slit SALT/RSS and integral-field VLT/MUSE spectral data to study the stellar and ionized gas …

ABSTRACT Several cosmological observations [e.g. cosmic microwave background (CMB), supernovae Type Ia, and local distance ladder measurements such as Cepheids] have been used to measure the global expansion rate of the Universe, i.e. the Hubble constant, $H_{0}$. However, these precision measurements have …

ABSTRACT We present an interstellar medium and stellar population analysis of three spectroscopically confirmed z > 7 galaxies in the Early Release Observations JWST/NIRCam and JWST/NIRSpec data of the SMACS J0723.3−7327 cluster. We use the Bayesian spectral energy distribution-fitting code prospector with …

ABSTRACT We present spatially resolved two-dimensional maps and radial trends of the stellar populations and kinematics for a sample of six compact elliptical galaxies (cE) using spectroscopy from the Keck Cosmic Web Imager (KCWI). We recover their star formation histories, finding that …
