A weak lensing analysis of the PLCK G100.2-30.4 cluster

M. Radovich, I. Formicola, M. Meneghetti +12

We present a mass estimate of the Planck-discovered cluster PLCK G100.2-30.4, derived from a weak lensing analysis of deep SUBARU griz images. We perform a careful selection of the…

Broadband distortion modeling in Lyman- forest BAO fitting

Michael Blomqvist, David Kirkby, Julian E. Bautista +8

In recent years, the Lyman- absorption observed in the spectra of high-redshift quasars has been used as a tracer of large-scale structure by means of the three-dimensional Lyma…

Gamma-ray observations of blazars and the intergalactic magnetic field spectrum

Chiara Caprini, Stefano Gabici

Very-high energy observations of blazars can be used to constrain the strength of the intergalactic magnetic field. A simplifying assumption which is often made is that of a magnet…

Structural properties of artificial halos in non-standard dark matter simulations

Shankar Agarwal, Pier Stefano Corasaniti

Artificial fragmentation of the matter density field causes the formation of spurious groups of particles in N-body simulations of non-standard Dark Matter (DM) models which are ch…

Weak lensing reconstructions in 2D & 3D: implications for cluster studies

Adrienne Leonard, Francois Lanusse, Jean-Luc Starck

We compare the efficiency with which 2D and 3D weak lensing mass mapping techniques are able to detect clusters of galaxies using two state-of-the-art mass reconstruction technique…

Chandra and XMM-Newton Observations of the Bimodal Planck SZ-detected Cluster PLCKG345.40-39.34 (A3716) with High and Low Entropy Subcluster Cores

Felipe Andrade-Santos, Christine Jones, William R. Forman +11

We present results from Chandra, XMM-Newton, and ROSAT observations of the Planck SZ-detected cluster A3716 (PLCKG345.40-39.34 - G345). We show that G345 is, in fact, two subcluste…
