MApping the Most Massive Overdensities Through Hydrogen (MAMMOTH) I: Methodology
Zheng Cai, Xiaohui Fan, Sebastien Peirani +8
Modern cosmology predicts that a galaxy overdensity is associated to a large reservoir of the intergalactic gas, which can be traced by the Ly forest absorption. We have underta…
A pilot ASKAP survey of radio transient events in the region around the intermittent pulsar PSR J1107-5907
G. Hobbs, I. Heywood, M. E. Bell +75
We use observations from the Boolardy Engineering Test Array (BETA) of the Australian Square Kilometre Array Pathfinder (ASKAP) telescope to search for transient radio sources in t…
Lessons learnt from the Solar neighbourhood and the Kepler field
Luca Casagrande
Setting the timeline of the events which shaped the Milky Way disc through its 13 billion year old history is one of the major challenges in the theory of galaxy formation. Achievi…
Constraints on Gravitino Decay and the Scale of Inflation using CMB spectral distortions
Emanuela Dimastrogiovanni, Lawrence M. Krauss, Jens Chluba
If local supersymmetry is the correct extension of the standard model of particle physics, then following Inflation the early universe would have been populated by gravitinos produ…
Deja Vu All Over Again: The Reappearance of Supernova Refsdal
P. L. Kelly, S. A. Rodney, T. Treu +21
In Hubble Space Telescope (HST) imaging taken on 10 November 2014, four images of supernova (SN) "Refsdal" (redshift z=1.49) appeared in an Einstein-cross--like configuration (imag…
Major Substructure in the M31 Outer Halo: the East Cloud
B. McMonigal, N. F. Bate, A. R. Conn +8
We present the first detailed analysis of the East Cloud, a highly disrupted diffuse stellar substructure in the outer halo of M31. The core of the substructure lies at a projected…
