Dynamics of tidal dwarf galaxies in the system Arp 72

Osvan M. Portilla-Narvaez, Javier Zaragoza-Cardiel, Gisela N. Ortiz-León +6

Some interactions between galaxies produce tidal tails primarily composed of material from their disks. Within these tails, concentrations of gas and stars can form, resembling dwa…

MeerKAT HI observations of Low Surface Brightness/Ultradiffuse Galaxy Candidates Projected around Two Southern Loose Groups

Chandreyee Sengupta, Tom C. Scott, Hao Chen +9

A large catalogue of low surface brightness galaxies (LSBGs) from the Dark Energy Survey showed significant clustering around nearby galaxy groups and clusters. Using the HIPASS su…

High-resolution HI mapping of nearby extremely metal-poor blue compact dwarf galaxies

Tom C. Scott, Elias Brinks, Chandreyee Sengupta +1

Optical observations of Blue Compact Dwarf galaxies (BCDs) show they typically have high specific star formation rates and low metallicites. A subset of these galaxies (those with…

Catalogue of nearby blue and near-solar gas metallicity SDSS dwarf galaxies

Yan Guo, Chandreyee Sengupta, Tom. C. Scott +2

A less explored aspect of dwarf galaxies is their metallicity evolution. Generally, dwarfs have lower metallicities than Hubble sequence late type galaxies but in reality, dwarfs s…

HI in high gas-phase metallicity dwarf galaxy WISEA J230615.06+143927.9

Yan Guo, C. Sengupta, T. C. Scott +2

We present resolved GMRT HI observations of the high gas-phase metallicity dwarf galaxy WISEA J230615.06+143927.9 (z = 0.005) (hereafter J2306) and investigate whether it could be…

Rejuvenating Star Formation Activity in an Early-type Dwarf Galaxy, LEDA 1915372, with Accreted HI Gas

Sanjaya Paudel, Suk-Jin Yoon, Omkar Bait +5

We report a rare astrophysical phenomenon, in which an early-type dwarf galaxy (dE), LEDA 1915372, is accreting gas from a nearby star-forming dwarf galaxy, MRK 0689, and is rejuve…
