Optical spectroscopy of high redshift BL Lac objects
Renato Falomo, Aldo Treves, Simona Paiano +1
BL Lac objects (BLL) are defined by the presence of very weak (typically 5 Å) or even absent spectral lines. This makes determining their distance particularly challenging, esp…
Gravity anomaly from laboratory experiments to astrophysics
Riccardo Scarpa, Renato Falomo, Aldo Treves
Modifications to Newtonian dynamics at low accelerations have long been proposed as an alternative to dark matter to explain galaxy rotation curves. More recently, similar correcti…
SDSS low z quasar companion galaxies
D. Bettoni, R. Falomo, S. Paiano
We investigate the relationship between quasars and close companion galaxies using photometry and spectroscopy from the large data set of the SDSS DR16 survey. From the SDSS-QSO ca…
Swift Observations of Gaia BH3
Boris Sbarufatti, Renato Falomo, Aldo Treves
We present UV and X-ray observations, obtained with the Swift Observatory, of Gaia BH3 a binary system containing a 33 solar masses black hole discovered through Gaia astrometry. T…
The Spectra of IceCube Neutrino (SIN) candidate sources -- V. Modeling and interpretation of multiwavelength and neutrino data
Xavier Rodrigues, Martina Karl, Paolo Padovani +5
A correlation has been reported between the arrival directions of high-energy IceCube events and gamma-ray blazars classified as intermediate- and high-synchrotron-peaked BL Lacs.…
Changing Look of the optical spectrum of the MeV Blazar PKS 0446+112 (4FGL J0449.1+1121)
Simona Paiano, Renato Falomo, Aldo Treves +2
Following the high activity of the gamma-ray Fermi source 4FGL J0449.1+1121 (PKS 0446+112), possibly associated with a IceCube neutrino event IC-240105A, we obtained optical spectr…
