The Blue Compact Dwarf Galaxy VCC 848 Formed by Dwarf-Dwarf Merging: HI Gas, Star Formation and Numerical Simulations
Hong-Xin Zhang, Rory Smith, Se-Heon Oh +12
A clear link between a dwarf-dwarf merger event and enhanced star formation (SF) in the recent past was recently identified in the gas-dominated merger remnant VCC 848, offering by…
Starbursting Nuclei in Old Dwarf Galaxies
Sanjaya Paudel, Suk-Jin Yoon
Nuclei of early-type dwarf galaxies (dEs) are usually younger than the galaxy main body, and such discrepancy in age has been a puzzle. To explore the origin of young nuclei in dEs…
Census and classification of low-surface-brightness structures in nearby early-type galaxies from the MATLAS survey
Michal Bílek, Pierre-Alain Duc, Jean-Charles Cuillandre +9
The morphology of galaxies gives essential constraints on the models of galaxy evolution. The morphology of the features in the low-surface-brightness regions of galaxies has not b…
A spectroscopic study of MATLAS-2019 with MUSE: an ultra-diffuse galaxy with an excess of old globular clusters
Oliver Müller, Francine R. Marleau, Pierre-Alain Duc +10
The MATLAS deep imaging survey has uncovered a plethora of dwarf galaxies in the low density environment it has mapped. A fraction of them are unusually extended and have a low-sur…
MCG+07-20-052: Interacting dwarf pair in a group environment
Sanjaya Paudel Chandreyee Sengupta, Suk-Jin Yoon, Daya Nidhi Chhatkuli
We present an observational study of the interacting pair of dwarf galaxies, MCG+07-20-052, in the vicinity of Milky Way mass spiral galaxy NGC 2998. MCG+07-20-052 is located at a…
The Blue Compact Dwarf Galaxy VCC848 Formed by Dwarf-Dwarf Merging
Hong-Xin Zhang, Sanjaya Paudel, Rory Smith +8
It has long been speculated that many starburst or compact dwarf galaxies are resulted from dwarf-dwarf galaxy merging, but unequivocal evidence for this possibility has rarely bee…
