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…
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…
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…
Spectroscopy of a Sample of Unidentified Gamma-ray Fermi Sources
Alberto Ulgiati, Simona Paiano, Aldo Treves +5
The fourth-DR3 version (4FGL-DR3) of the Fermi/LAT catalogue of -ray sources contains 1000 objects at a galactic latitude |b| > 10 which are not identified with…
ZBLLAC -- A spectroscopic database of BL Lacertae objects
M. Landoni, R. Falomo, S. Paiano +1
This paper describes the database of optical spectra of BL Lacertae (BLL) objects ZBLLAC available at the URL https://web.oapd.inaf.it/zbllac/. At the present date, it contains cal…
