On the Existence, Rareness, and Uniqueness of Quenched H i-rich Galaxies in the Local Universe
Using data from ALFALFA, xGASS, H i -MaNGA, and the Sloan Digital Sky Survey (SDSS), we identify a sample of 47 “red but H i -rich” (RR) galaxies with near-UV (NUV) − r > 5 and unusually high H i -to-stellar mass ratios. We compare the optical properties

Measurements of Magnetic Fields in Interstellar Clouds of Neutral Hydrogen
A new series of measurements of the Zeeman splitting of 21-cm spectral lines has revealed strong (> 10−5 G) magnetic field effects in several neutral hydrogen clouds in the direction of HII regions. Low limits have been set to the line-of-sight field components in six other regions of space.

Cold neutral hydrogen (H i ) is a crucial precursor for molecular gas formation and can be studied via H i absorption. This study investigates H i absorption in low column density regions of the Small and Large Magellanic Clouds (SMC and LMC) using the ...

THE MATHEMATICAL MODELING OF THE PROCESS OF NEUTRALIZATION CLOUDS OF HYDROGEN CYANIDE
A computer model to calculate the neutralization of НСN cloud is proposed. The model is based on the numerical integration of the 3-D gradient transport model. The results of numerical experiment are presented.

The presence of dense, neutral hydrogen clouds in the hot, diffuse intragroup and intracluster (IC) medium is an important clue to the physical processes controlling the survival of cold gas and sheds light on cosmological baryon flows in massive halos ...

Origin of the Multiphase Interstellar Medium: The Effects of Turbulence and Magnetic Field
The interstellar medium (ISM) consists of multiphase gas, including the warm neutral medium (WNM), the unstable neutral medium (UNM), and the cold neutral medium (CNM).

On The Origin Of Neutral Hydrogen Clouds In Nearby Galaxy Groups: The Role Of Galaxy Interactions
This thesis addresses the origin of the High Velocity Clouds (HVCs) observed around the Milky Way and other nearby galaxies. Such clouds are likely created through a combination of galactic fountains, galaxy interactions, dark matter substructure, and ...
