Galaxy clusters are extreme environments where interactions with the hot intracluster medium drive rapid galaxy evolution. These processes can result in the formation of...

We present a sample of low HI mass (M_HI_<10^8^M_{sun}_) dwarf galaxies detected by The FAST All Sky HI Survey (FASHI) project. Due to the faint and irregular morphology of...

Obtaining a complete census of gas in the local interstellar medium (LISM; <100pc) is challenging given the limited available tracers of the warm, partially ionized medium....

We assess archival high-energy data for key stars on the Habitable Worlds Observatory (HWO) Target Stars and Systems 2025 list, as stellar radiation is critical to shaping and...

The Local Void is one of the nearest large voids, located at a distance of 23Mpc. It lies largely behind the Galactic Bulge and is therefore extremely difficult to observe. We...

Galaxy morphology in atomic hydrogen (H I) and in the ultraviolet (UV) are closely linked. This has motivated their combined use to quantify morphology over the full H I disc...

The COSMOS H I Large Extragalactic Survey (CHILES) Continuum and Polarization survey is an ultradeep continuum imaging study of the COSMOS field conducted using the Karl G....

We examine the H I gas kinematics of galaxy pairs in two clusters and a group using Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pilot survey observations. We...

Using the Five-hundred-meter Aperture Spherical radio Telescope, we have performed an Ursa Major supergroup HI survey covering the entire UMa region centered at...

We present high-resolution rotation curves and mass models of 26 dwarf galaxies from "Local Irregulars That Trace Luminosity Extremes, The H_I_ Nearby Galaxy Survey" (LITTLE...

We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The HI Nearby Galaxy Survey), which is aimed at determining what drives star formation in dwarf...

The 'Local Volume HI Survey' (LVHIS) comprises deep HI spectral line and 20-cm radio continuum observations of 82 nearby, gas-rich galaxies, supplemented by multiwavelength...

Results of HI observations with the 100-m Effelsberg radio telescope are presented for 94 edge-on spiral galaxies from the Revised Flat Galaxy Catalog (Karachentsev et al.,...

We present the first estimate of the Ly{alpha} luminosity function using blind spectroscopy from the Multi Unit Spectroscopic Explorer, MUSE, in the Hubble Deep Field-South....

We have selected a sample of 41 extremely isolated galaxies (EIGs) from the local Universe using both optical and HI Arecibo Legacy Fast ALFA survey redshifts. Narrow-band...

We have developed a parallel code called the VoIgt profile Parameter Estimation Routine (VIPER) for automatically fitting the HI Ly{alpha} forest seen in the spectra of...

We present the results from our survey of HI 21-cm absorption, using Giant Metrewave Radio Telescope, Very Large Array and Westerbork Radio Synthesis Telescope, in a sample of...

The application of artificial neural networks (ANNs) for the estimation of HI gas mass fraction (M_HI_/M) is investigated, based on a sample of 13 674 galaxies in the Sloan...

The star-forming reservoir in the distant Universe can be detected through HI 21-cm absorption arising from either cool gas associated with a radio source or from within a...

We present results of a blind 21cm HI-line imaging survey of a galaxy overdensity located behind the Milky Way at l, b ~= 160{deg}, 0.5{deg}. The overdensity corresponds to a...
