Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Pascal M. Keller, Bojan Nikolic, Nithyanandan Thyagarajan, Chris L. Carilli, Gianni Bernardi | Summary: Radio interferometers aiming to measure the power spectrum of the redshifted 21 cm line during the Epoch of Reionisation (EoR) need to achieve an unprecedented dynamic range to separate the weak signal […]

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Mayuko Yamashita, Kazuya Yonekura, , | Summary: For physicists: For supersymmetric quantum mechanics, there are cases when a mod-2 Witten index can be defined, even when a more ordinary $mathbb{Z}$-valued Witten index vanishes. Similarly, for 2d supersymmetric quantum field theories, there are cases when a […]

Kavli Affiliate: Roger Blandford | First 5 Authors: Noemie Globus, Roger Blandford, , , | Summary: Understanding the acceleration of Ultra High Energy Cosmic Rays is one of the great challenges of contemporary astrophysics. In this short review, we summarize the general observational constraints on their composition, spectrum and isotropy which indicate that nuclei heavier […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Sergey S. Tsygankov, Victor Doroshenko, Alexander A. Mushtukov, Juri Poutanen, Alessandro Di Marco | Summary: X-ray polarimetry is a unique way to probe the geometrical configuration of highly magnetized accreting neutron stars (X-ray pulsars). GRO J1008$-$57 is the first transient X-ray pulsar observed at two different flux […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Akira Tokiwa, Masahiro Takada, Tian Qiu, Naoki Yasuda, Yutaka Komiyama | Summary: We use the Subaru Hyper Suprime-Cam (HSC) data to study structural parameters and systemic proper motion of the Sextans dwarf spheroidal galaxy at the heliocentric distance of 86 kpc, which is one of the most […]
