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…

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…

The spectra of IceCube Neutrino (SIN) candidate sources -- III. Optical spectroscopy and source characterization of the full sample

Simona Paiano, Renato Falomo, Aldo Treves +5

A correlation between astrophysical high-energy neutrinos and blazars has been suggested by various authors. In particular, a likely association between IceCube events and intermed…

Virial theorem in clusters of galaxies with MOND

M. Lopez-Corredoira, J. E. Betancort-Rijo, R. Scarpa +1

A specific modification of Newtonian dynamics known as MOND has been shown to reproduce the dynamics of most astrophysical systems at different scales without invoking non-baryonic…

On the Orbital Velocity of Isolated Galaxy Pairs: II Accurate MOND Predictions

Riccardo Scarpa, Renato Falomo, Aldo Treves

Examining a catalogue of isolated galaxy pairs, a preferred orbital intervelocity of ~150 km/s was recently reported. This discovery is difficult to reconcile with the expectations…
