Extended Gravity Cosmography

open access: yes, 2019
Cosmography can be considered as a sort of a model-independent approach to tackle the dark energy/modified gravity problem. In this review, the success and the shortcomings of the $\Lambda$CDM model, based on General Relativity and standard model of ...

Broad Absorption Line Variability in Radio-Loud Quasars [PDF]

open access: yes, 2014
We investigate C IV broad absorption line (BAL) variability within a sample of 46 radio-loud quasars (RLQs), selected from SDSS/FIRST data to include both core-dominated (39) and lobe-dominated (7) objects.

An introduction to local Black Hole horizons in the 3+1 approach to General Relativity

open access: yes, 2011
We present an introduction to dynamical trapping horizons as quasi-local models for black hole horizons, from the perspective of an Initial Value Problem approach to the construction of generic black hole spacetimes.

Elliptical Galaxy in the Making: The Dual Active Galactic Nuclei and Metal-enriched Halo of Mrk 273 [PDF]

open access: yes, 2019
A systematic analysis of the X-ray emission from the nearby ultraluminous infrared galaxy Mrk 273 was carried out by combining new 200 ksec Chandra data with archived 44 ksec data.

Mode spectrum of the electromagnetic field in open universe models [PDF]

open access: yes, 2017
We examine the mode functions of the electromagnetic field on spherically symmetric backgrounds with special attention to the subclass which allows for a foliation as open Friedmann-Lemaître (FL) space-time.

Dark Energy Survey Year 1 results: weak lensing mass calibration of redMaPPer galaxy clusters [PDF]

open access: yes, 2018
We constrain the mass--richness scaling relation of redMaPPer galaxy clusters identified in the Dark Energy Survey Year 1 data using weak gravitational lensing. We split clusters into 4×3 bins of richness λ and redshift z for λ≥20 and 0.2≤z≤0.65 and

From Swampland to Phenomenology and Back

open access: yes, 2019
Swampland conjectures are a set of proposed necessary conditions for a low-energy effective field theory to have a UV completion inside a theory of quantum gravity.

Astronomical Dating and the Internal Chronology of the Pentateuch [PDF]

open access: yes, 2013
Some of the narratives in the Pentateuch can be associated with known astronomical events to provide absolute dates for biblical chronology.Comment: 29 pages, 12 ...
