HI imaging of dwarf star-forming galaxies: Masses, morphologies and gas deficiencies
Sumit Jaiswal, Amitesh Omar
The GMRT observations of the HI 21~cm-line emission from 13~nearby dwarf star-forming galaxies are presented. The ranges of star formation rates and stellar masses of the sample ga…
Narrowband H imaging of nearby Wolf-Rayet galaxies
A. Paswan, Kanak Saha, A. Omar
We present narrowband H imaging of nearby Wolf-Rayet (WR) galaxies known as a subset of starburst galaxies. The H images have been used to show morphology of star-forming reg…
Role of intracluster supernovae in radio mini-halos in galaxy clusters
Amitesh Omar
A possibility of generating a population of cosmic-ray particles accelerated in supernovae typeIa (SNIa) remnants in the intracluster medium (ICM) is discussed. The presently const…
Optical spectroscopy of star-forming regions in dwarf Wolf-Rayet galaxies
A. Paswan, A. Omar, S. Jaiswal
We present here spatially-resolved optical spectroscopic observations of four nearby dwarf Wolf-Rayet (WR) galaxies. The ages of the most recent starburst events in these galaxies…
Devasthal Fast Optical Telescope observations of Wolf-Rayet dwarf galaxy Mrk 996
S. Jaiswal, A. Omar
The Devasthal Fast Optical Telescope (DFOT) is a 1.3 meter aperture optical telescope, recently installed at Devasthal, Nainital. We present here the first results using an \Ha fil…
