Initial Conditions for Idealised Clusters Mergers, simulating El Gordo
J. M. F. Donnert
Simulations of isolated binary mergers of galaxy clusters are a useful tool to study the evolution of these objects. For exceptionally massive systems they even represent the only…
The First Pulse of the Extremely Bright GRB 130427A: A Test Lab for Synchrotron Shocks
R. Preece, J. Michael Burgess, A. von Kienlin +156
Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever observed. The initial pulse up to 2.5 s is possibly the brightest well-isolated pulse observed to date. A fine…
New detections of radio minihalos in cool cores of galaxy clusters
Simona Giacintucci, Maxim Markevitch, Tiziana Venturi +3
Cool cores of some galaxy clusters exhibit faint radio "minihalos." Their origin is unclear; their study has been limited by their small number. We undertook a systematic search fo…
Discovery of Megaparsec-Scale, Low Surface Brightness Nonthermal Emission in Merging Galaxy Clusters using the Green Bank Telescope
Damon Farnsworth, Lawrence Rudnick, Shea Brown +1
We present results on 12 X-ray bright clusters observed at 1.4 GHz with the Green Bank Telescope. After subtraction of point sources, we reach a median (best) 1-sigma noise level o…
Physical properties in young radio sources. VLBA observations of high frequency peaking radio sources
M. Orienti, D. Dallacasa
Multifrequency Very Long Baseline Array (VLBA) observations were performed to study the radio morphology and the synchrotron spectra of four high frequency peaking radio sources. T…
An optical spectroscopic survey of the 3CR sample of radio galaxies with z<0.3. V. Implications for the unified model for FRIIs
Ranieri D. Baldi, Alessandro Capetti, Sara Buttiglione +2
We explore the implications of our optical spectroscopic survey of 3CR radio sources with z<0.3 for the unified model (UM) for radio-loud AGN, focusing on objects with a FRII radio…
A sensitive study of the peculiar jet structure HST-1 in M87
Carolina Casadio, José L. Gómez, Marcello Giroletti +5
To obtain a better understanding of the location and mechanisms for the production of the gamma-ray emission in jets of AGN we present a detailed study of the HST-1 structure, 0.8…
The TeV blazar Markarian 421 at the highest spatial resolution
M. G. Blasi, R. Lico, M. Giroletti +14
We report the results obtained for the AGN Markarian 421 by model-fitting the data in the visibility plane, studing the proper motion of jet components, the light curve, and the sp…
The spectral index image of the radio halo in the cluster Abell 520 hosting a famous bow shock
V. Vacca, L. Feretti, G. Giovannini +4
Synchrotron radio emission is being detected from an increasing number of galaxy clusters. Spectral index images are a powerful tool to investigate the origin, nature, and connecti…
