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$-$57 is the first transient X-ray pulsar observed at two different flux […]
Kavli Affiliate: R. Glenn Morris | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Matthew Kaplan, Peter Orel, Kevan Donlon | Summary: The Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge detector output stage for charge-coupled device (CCD) image sensors. Developed at MIT Lincoln Laboratory, this technology uses a p-MOSFET transistor with a […]
Kavli Affiliate: Risa Wechsler | First 5 Authors: Jinyi Yang, Xiaohui Fan, Ansh Gupta, Adam Myers, Nathalie Palanque-Delabrouille | Summary: We report the first results of a high-redshift ($z$ >~ 5) quasar survey using the Dark Energy Spectroscopic Instrument (DESI). As a DESI secondary target program, this survey is designed to carry out a systematic […]

Kavli Affiliate: Roger Blandford | First 5 Authors: Payel Mukhopadhyay, Enrico Peretti, Noemie Globus, Paul Simeon, Roger Blandford | Summary: The origin of cosmic rays above the knee in the spectrum is an unsolved problem. We present a wind model in which interstellar gas flows along a non-rotating, expanding flux tube with a changing speed […]

Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Donald M. Hassler, Sarah E Gibson, Jeffrey S Newmark, Nicholas A. Featherstone, Lisa Upton | Summary: Solaris is a transformative Solar Polar Discovery-class mission concept to address crucial outstanding questions that can only be answered from a polar vantage. Solaris will image the Sun’s poles from […]
Kavli Affiliate: Noah A. Kurinsky | First 5 Authors: Sebastian Baum, Patrick Stengel, Natsue Abe, Javier F. Acevedo, Gabriela R. Araujo | Summary: Minerals are solid state nuclear track detectors – nuclear recoils in a mineral leave latent damage to the crystal structure. Depending on the mineral and its temperature, the damage features are retained […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Elise Darragh-Ford, John F. Wu, Yao-Yuan Mao, Risa H. Wechsler, Marla Geha | Summary: We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method. Our selection consists of a […]
