Revealing the structure of the lensed quasar Q 0957+561 III. Constraints on the size of the broad-line region
C. Fian, J. A. Muñoz, E. Mediavilla +6
Our aim is to examine the size, kinematics, and geometry of the broad-line region (BLR) in the double-lensed quasar Q 0957+561 by analyzing the impact of microlensing on various re…
Black Hole masses for 14 gravitational lensed quasars
A. Melo, V. Motta, J. Mejía-Restrepo +7
We estimate black hole masses (M) for 14 gravitationally lensed quasars using the Balmer lines along with estimates based on MgII and CIV emission lines for four and two…
Constraining uber gravity with recent observations and studying the problem
Gustavo A. Concha Valdez, Claudia Quintanilla, Miguel A. García-Aspeitia +2
This paper studies both CDM and CDM models under the über gravity theory, named üCDM and üCDM respectively. We report bounds over their parameter phase-space using several co…
STRIDES: Automated uniform models for 30 quadruply imaged quasars
T. Schmidt, T. Treu, S. Birrer +68
Gravitational time delays provide a powerful one step measurement of , independent of all other probes. One key ingredient in time delay cosmography are high accuracy lens mod…
Observational constraints and dynamical analysis of Kaniadakis horizon-entropy cosmology
A. Hernández-Almada, Genly Leon, Juan Magaña +5
We study the scenario of Kanadiakis horizon entropy cosmology which arises from the application of the gravity-thermodynamics conjecture using the Kaniadakis modified entropy. The…
Kaniadakis holographic dark energy: observational constraints and global dynamics
A. Hernández-Almada, Genly Leon, Juan Magaña +4
We investigate Kaniadakis-holographic dark energy by confronting it with observations. We perform a Markov Chain Monte Carlo analysis using cosmic chronometers, supernovae type Ia,…
