A catalogue of dwarf galaxy candidates around interacting galaxies
, 1998 We present results from the imaging of a sample of 12 interacting galaxies for which we have cataloged all potential dwarf systems in the vicinity of these strongly interacting galaxies. After careful cleaning of the images and applying a restrictive S/N

The molecular gas content throughout the low-z merger sequence
The Open Journal of AstrophysicsExploiting IRAM 30 m CO spectroscopy, we find that SDSS post-merger galaxies display gas fractions and depletion times enhanced by 25-50\%, a mildly increased CO excitation, and standard molecular-to-atomic gas ratios, compared to non-interacting ...

FEASTS: Radial Distribution of H i Surface Densities Down to 0.01 M⊙ pc−2 of 35 Nearby Galaxies
The Astrophysical JournalWe present the H i surface density (Σ _H _i ) radial distributions based on total-power H i images obtained by FAST in the FEASTS program, for 35 galaxies with inclinations lower than 72°.

The clustering and X-ray properties of faint galaxies [PDF]
, 1994 The clustering properties of faint (23 ≤ B ≤ 27) galaxies were investigated, with the aim of obtaining information about their redshift distribution, N(z), and therefore about the processes of galaxy evolution causing the steep rise in the galaxy number ...

The Astrophysical JournalWe present a comprehensive investigation into the influence of stellar bars on star formation (SF) in galaxy pairs, using a large sample of low-redshift galaxies (0.02 < z < 0.08) from the DESI Legacy Imaging Surveys Data Release 8. Our analysis examines

The Complex Multiwavelength Morphology of the Peculiar Compact Galaxy Group IC 2431
The Astrophysical JournalWe present new Chandra X-ray imaging spectroscopy of the compact galaxy group IC 2431, and compare with archival ultraviolet, optical, infrared, and radio images. IC 2431 is a starburst system containing three tidally distorted disk galaxies.

The Astrophysical JournalGas accretion from both the circumgalactic medium (CGM)/intergalactic medium (IGM) and interacting companion galaxy can dilute the gas phase metallicity of a galaxy. However, their relative contribution to the chemical evolution of galaxies remains to be

Caught in the Cosmic Web: Evidence for Ram Pressure Stripping of a Low-mass Galaxy by the Cosmic Web
The Astrophysical Journal LettersWe present interferometric radio observations of the neutral atomic gas in AGC 727130, a low-mass, gas-rich field galaxy lacking significant star formation.

Molecular gas in interacting galaxies [PDF]
, 2001 grantor: University of TorontoA systematic study of the molecular gas properties in strongly interacting galaxies (SIGs) has been undertaken, which includes two parts: (1) a statistical study of a large, optically-selected, complete sample of ...

Surface photometry of early-type galaxies in rich clusters [PDF]
, 1998 This thesis investigates the morphology of early-type galaxies in two rich clusters using 2D surface photometry. In particular, the amount of light in the 'disk' component is focussed upon, as the presence of a disk is the main morphological criterion in
