As a fundamental parameter for modern cosmology, the Hubble constant H 0 is experiencing
a serious crisis. In this paper, we explore an independent approach to measure H 0 based …

In this work, we investigate neutron stars (NS) in\(f (\mathtt {R, L_m})\) theory of gravity for the
case\(f (\mathtt {R, L_m})=\mathtt {R}+\mathtt {L_m}+\sigma\mathtt {R}\mathtt {L_m}\), where\…

Cluster strong lensing cosmography is a promising probe of the background geometry of the
Universe and several studies have emerged thanks to the increased quality of observations …

1991T-like supernovae are the luminous, slow-declining extreme of the Branch shallow-silicon
(SS) subclass of Type Ia supernovae. They are distinguished by extremely weak Ca ii H …

The abundance distribution in the ejecta of the peculiar slowly declining Type Ia supernova (SN
Ia) SN 1999aa is obtained by modelling a time series of optical spectra. Similar to SN …

In view of the recent measurement of H 0 from the Hubble Space Telescope and Supernova
H0 for the Equation of State (SH0ES) team, we explore the possibility of existence of a …

Stellar evolution theory predicts multiple pathways to the explosive deaths of stars as supernovae.
Locating and characterizing the progenitors of well-studied supernovae is important to …

In this work, we perform a Bayesian statistical fit to estimate the mass-to-distance ratio and
the recessional redshift of 10 different black holes hosted at the centre of active galactic nuclei…

… Here we will exploit the widely used formulation proposed by Szapudi & Szalay (1998),
which provides an unbiased and with-minimal-variance estimator based on the counting of …

The interpretation of cosmological observations relies on a notion of an average Universe,
which is usually considered as the homogeneous and isotropic Friedmann-Lemaître-…
