A VLA-GMRT Look at 11 Powerful FR II Quasars
S. Vaddi, P. Kharb, R. A. Daly +5
We present results from 1.4 and 5 GHz observations at matched resolution with the Karl G. Jansky Very Large Array (VLA) of 11 powerful 3C FR II quasars. We examine the 11 quasars a…
A Curved 150 Parsec Long Jet in the Double-Peaked Emission-Line AGN KISSR 434
Preeti Kharb, Sravani Vaddi, Biny Sebastian +3
Double-peaked emission lines in the narrow- and/or broad-line spectra of AGN have been suggested to arise due to disky broad/narrow line regions, jet-medium interaction, or the pre…
A Tapered Gridded Estimator (TGE) for the Multi-Frequency Angular Power Spectrum (MAPS) and the Cosmological HI 21-cm Power Spectrum
Somnath Bharadwaj, Srijita Pal, Samir Choudhuri +1
In this work we present a new approach to estimate the power spectrum of redshifted HI 21-cm brightness temperature fluctuations. The MAPS complete…
An Image-based Tapered Gridded Estimator (ITGE) for the angular power spectrum
Samir Choudhuri, Prasun Dutta, Somnath Bharadwaj
We present the Image-based Tapered Gridded Estimator (ITGE) to measure the angular power spectrum of the sky signal directly from the visibilities measured in radio-in…
[CII] 158 Micron Emission from z~4 HI Absorption-Selected Galaxies
Marcel Neeleman, Nissim Kanekar, J. Xavier Prochaska +2
We report on a search for the [CII] 158 micron emission line from galaxies associated with four high-metallicity damped Ly-alpha absorbers (DLAs) at z ~ 4 using the Atacama Large M…
Very gas-rich extremely metal-poor blue void dwarfs
S. Pustilnik, Y. Perepelitsyna, A. Kniazev +2
Half-dozen of extreme representatives of void dwarf galaxy population were found in our study of evolutionary status of a hundred galaxies in the nearby Lynx-Cancer void. They are…
