The Emerging Population of High-energy Emitting Radio Galaxies
G. Bruni, V. S. Paliya, D. J. Saikia +22
High-energy emission from radio galaxies provides a unique laboratory to study the connection between accretion, jet formation, and particle acceleration in active galactic nuclei…
Mapping the emission and spectral properties of the FRI radio galaxy 3C 449 with LOFAR and the VLA
Luca Ricci, Luisa Ostorero, Raffaella Morganti +3
The jets and lobes of nearby radio galaxies are ideal laboratories to explore the spectral and dynamical evolution of the radio-emitting plasma that emanates from active galactic n…
Dynamics of dwarf galaxies in gravity
Ivan de Martino, Antonaldo Diaferio, Luisa Ostorero
We use the kinematic data of the stars in eight dwarf spheroidal galaxies to assess whether gravity can fit the observed profiles of the line-of-sight velocity dispersion of…
The proper motion of stars in dwarf galaxies: distinguishing central density cusps from cores
Ivan de Martino, Antonaldo Diaferio, Luisa Ostorero
We show that measuring the proper motion of stars within a dwarf galaxy, with an uncertainty of 1 km/s at most, can establish whether the Dark Matter (DM) density pro…
Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Probing the shape of the Milky Way dark matter halo with hypervelocity stars: a new method
Arianna Gallo, Luisa Ostorero, Sankha Subhra Chakrabarty +2
We propose a new method to determine the shape of the gravitational potential of the dark matter (DM) halo of the Milky Way (MW) with the galactocentric tangential velocities of a…
