Galactic-scale evolution of classical and complex radio galaxies. Impact of ambient morphology and jet geometry
Gourab Giri, Prajnadipt Ghosh, Ravi Joshi +9
Extragalactic jets exhibit a wide range of propagation orientations relative to the host galaxy's principal axis. This study investigate the spatiotemporal evolution of jets as a f…
Two Epochs of VLBI Observations of 8 KISSR Seyfert & LINER Galaxies: Suggestions of Fast and Filamentary Outflows
Preeti Kharb, Anderson Caproni, Salmoli Ghosh +4
We present here the results from a second epoch of phase-referenced VLBA observations of 8 Seyfert and LINER galaxies from the KISSR sample. These sources were chosen based on the…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
Parsec-scale jet precession and a putative supermassive binary black hole system in the blazar AO 0235+164
Flavio Benevenuto da Silva Junior, Anderson Caproni
The blazar AO 0235+164 is a key source for studying the interplay between multi-wavelength variability in its light curves and changes in the position angles and apparent velocitie…
Galactic transient sources with the Cherenkov Telescope Array Observatory
Cherenkov Telescope Array Observatory Consortium
A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…
Exploring the evolution of a dwarf spheroidal galaxy with SPH simulations: II. AGN feedback
R. Hazenfratz, P. Barai, G. A. Lanfranchi +1
We investigate AGN feedback from an intermediate-mass black hole at the center of a dwarf spheroidal galaxy, by performing isolated galaxy simulations using a modified version of t…
