VEGAS: VST Early-type GAlaxy Survey. V. IC 1459 group: Mass assembly history in low density environments
E. Iodice, M. Spavone, A. Cattapan +9
This paper is based on the multi-band VST Early-type GAlaxy Survey (VEGAS) with the VLT Survey Telescope (VST). We present new deep photometry of the IC1459 group in g and r band.…
The LOFAR view of NGC 3998, a sputtering AGN
Sarrvesh S. Sridhar, Raffaella Morganti, Kristina Nyland +3
Low-power radio sources dominate the radio sky. They tend to be small in size and core-dominated, but the origin of their properties and the evolution of their radio plasma are not…
Mapping the dark matter halo of early-type galaxy NGC 2974 through orbit-based models with combined stellar and cold gas kinematics
Meng Yang, Ling Zhu, Anne-Marie Weijmans +4
We present an orbit-based method of combining stellar and cold gas kinematics to constrain the dark matter profile of early-type galaxies. We apply this method to early-type galaxy…
ALMA observations of PKS 1549-79: a case of feeding and feedback in a young radio quasar
Tom Oosterloo, Raffaella Morganti, Clive Tadhunter +4
We present CO(1-0) and CO(3-2) ALMA observations of the molecular gas in PKS 1549-79, as well as mm and VLBI 2.3-GHz continuum observations of its radio jet. PKS 1549-79 is one of…
Baryon dominated ultra-diffuse galaxies
Pavel E. Mancera Piña, Filippo Fraternali, Elizabeth A. K. Adams +1
By means of interferometic 21-cm observations and a 3D kinematic modeling technique, we study the gas kinematics of six HI-rich ultra-diffuse galaxies (UDGs). We derive robust circ…
HALOGAS: the properties of extraplanar HI in disc galaxies
A. Marasco, F. Fraternali, G. Heald +9
We present a systematic study of the extraplanar gas (EPG) in a sample of 15 nearby late-type galaxies at intermediate inclinations using publicly available, deep interferometric H…
Off the baryonic Tully-Fisher relation: a population of baryon-dominated ultra-diffuse galaxies
Pavel E. Mancera Piña, Filippo Fraternali, Elizabeth A. K. Adams +17
We study the gas kinematics traced by the 21-cm emission of a sample of six HIrich low surface brightness galaxies classified as ultra-diffuse galaxies (UDGs). Using the 3D kine…
Feedback from low-luminosity radio galaxies: B2 0258+35
Suma Murthy, Raffaella Morganti, Tom Oosterloo +6
Low-luminosity radio-loud active galactic nuclei (AGN) are of importance in studies concerning feedback from radio AGN since a dominant fraction of AGN belong to this class. We rep…
An accurate low-redshift measurement of the cosmic neutral hydrogen density
Wenkai Hu, Laura Hoppmann, Lister Staveley-Smith +7
Using a spectral stacking technique, we measure the neutral hydrogen (HI) properties of a sample of galaxies at across 35 pointings of the Westerbork Synthesis Radio Tel…
Neutral hydrogen gas within and around NGC 1316
P. Serra, F. M. Maccagni, D. Kleiner +20
We present MeerKAT observations of neutral hydrogen gas (HI) in the nearby merger remnant NGC 1316 (Fornax A), the brightest member of a galaxy group which is falling into the Forn…
The parsec-scale structure of jet-driven HI outflows in radio galaxies
Raffaella Morganti, Robert Schulz, Kristina Nyland +4
Radio jets can play multiple roles in the feedback loop by regulating the accretion of the gas, by enhancing gas turbulence, and by driving gas outflows. Numerical simulations are…
