Beyond general relativity: probing gravity with gravitational redshifts
Eleni Tsaprazi, Giorgio F. Lesci, Federico Marulli +7
Despite the success of general relativity (GR), the unexplained nature of dark energy on cosmological scales leaves open the question of whether GR provides a complete description…
The powerful lens galaxy cluster PLCK G287.0+32.9 ()
Maurizio D'Addona, Amata Mercurio, Piero Rosati +17
We present a new high-precision strong lensing model of PLCK G287.032.9, a massive lens galaxy cluster at , with the aim to get an accurate estimation of its effective…
An improved Magellan weak lensing analysis of the galaxy cluster Abell 2744
Davide Abriola, Daniele Della Pergola, Marco Lombardi +4
We present a new weak lensing analysis of the Hubble Frontier Fields galaxy cluster Abell 2744 ( = 0.308) using new Magellan/MegaCam multi-band imaging data. We carry out…
Augmenting the power of time-delay cosmography in lens galaxy clusters by probing their member galaxies I. Type Ia supernovae
A. Acebron, S. Schuldt, C. Grillo +9
We present a simple and promising new method to measure the expansion rate and the geometry of the universe that combines observations related to the time delays between the multip…
Deep U band and R imaging of GOODS-South: Observations,data reduction and first results
M. Nonino, M. Dickinson, P. Rosati +9
We present deep imaging in the {\em U} band covering an area of 630 arcmin centered on the southern field of the Great Observatories Origins Deep Survey (GOODS). The data wer…
