Exploring departures from Schwarzschild black hole in gravity
Vittorio De Falco, Francesco Bajardi, Rocco D'Agostino +2
Different astrophysical methods can be combined to detect possible deviations from General Relativity. In this work, we consider a class of gravity models selected by the ex…
H2CN/H2NC abundance ratio: a new potential temperature tracer for the interstellar medium
David San Andrés, Laura Colzi, Víctor M. Rivilla +7
The radical is the high-energy metastable isomer of radical, which has been recently detected for the first time in the interstellar medium towards a ha…
Positivity Conditions for Generalised Schwarzschild Space-Times
A. D'Alise, G. Fabiano, D. Frattulillo +4
We analyse the impact of positivity conditions on static spherically symmetric deformations of the Schwarzschild space-time. The metric is taken to satisfy, at least asymptotically…
Quasars as high-redshift standard candles
Guido Risaliti, Elisabeta Lusso, Emanuele Nardini +5
In the past few years, we built a Hubble diagram of quasars up to redshift z7, based on the nonlinear relation between quasars' x-ray and UV luminosities. Such a Hubble diagr…
Gamma-Ray Bursts, Quasars, Baryonic Acoustic Oscillations, and Supernovae Ia: new statistical insights and cosmological constraints
G. Bargiacchi, M. G. Dainotti, S. Nagataki +1
The recent Hubble constant, , tension is observed between the value of from the Cosmic Microwave Background (CMB) and Type Ia Supernovae (SNe Ia). It i…
Propagation of light in the presence of gravity generated by static and spherically symmetric curved space-times using Maxwell equations
Enderson Falcón-Gómez, Adrián Amor-Martín, Valentín De La Rubia +3
In this manuscript, we present an alternative method for calculating null geodesics in General Static Isotropic Metrics in General Relativity and Extended Theories of Gravity. By a…
