Detection of persistent VHE gamma-ray emission from PKS 1510-089 by the MAGIC telescopes during low states between 2012 and 2017
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +165
PKS 1510-089 is a flat spectrum radio quasar strongly variable in the optical and GeV range. We search for low-state VHE gamma-ray emission from PKS 1510-089. We aim to characteriz…
The primordial environment of super massive black holes: large scale galaxy overdensities around QSOs with LBT
L. Morselli, M. Mignoli, R. Gilli +8
We investigated the presence of galaxy overdensities around four QSOs, namely SDSS J1030+0524 (z = 6.28), SDSS J1148+5251 (z = 6.41), SDSS J1048+4637 (z = 6.20) and SDSS J…
Dwarf spheroidal satellites of M31: I. Variable stars and stellar populations in Andromeda XIX
Felice Cusano, Gisella Clementini, Alessia Garofalo +9
We present B,V time-series photometry of Andromeda XIX (And XIX), the most extended (half-light radius of 6.2') of Andromeda's dwarf spheroidal companions, that we observed with th…
A low escape fraction of ionizing photons of L>L* Lyman break galaxies at z=3.3
K. Boutsia, A. Grazian, E. Giallongo +12
We present an upper limit for the relative escape fraction (f_{esc}^{rel}) of ionizing radiation at z~3.3 using a sample of 11 Lyman Break Galaxies (LBGs) with deep imaging in the…
The isolated neutron star RBS1774 revisited. Revised XMM-Newton X-ray parameters and an optical counterpart from deep LBT-observations
A. Schwope, T. Erben, J. Kohnert +12
We report optical B-band observations with the Large Binocular Telescope LBT of the isolated neutron star RBS1774. The stacked image with total exposure 2.5h reveals a candidate op…
