Extreme Energy Cosmic Rays “Treasure Maps”: a new methodology to unveil the nature of cosmic accelerators

Kavli Affiliate: Roger Blandford | First 5 Authors: Noémie Globus, Anatoli Fedynitch, Roger Blandford, , | Summary: Extreme Energy Cosmic Rays, EECRs — cosmic rays with energies beyond the GZK cutoff (i.e. greater than 100 EeV) are scarce. Only a few of such events have been detected by air shower experiments and the nature of […]

NuSTAR Observations of Abell 665 and 2146: Constraints on Non-Thermal Emission

Kavli Affiliate: Grzegorz Madejski | First 5 Authors: Randall Rojas Bolivar, Daniel Wik, Ayşegül Tümer, Fabio Gastaldello, Julie Hlavacek-Larrondo | Summary: Observations from past missions such as RXTE and Beppo-SAX suggested the presence of inverse Compton (IC) scattering at hard X-ray energies within the intracluster medium of some massive galaxy clusters. In subsequent years, observations […]

Photometry, Centroid and Point-Spread Function Measurements in the LSST Camera Focal Plane Using Artificial Stars

Kavli Affiliate: Aaron Roodman | First 5 Authors: Johnny H. Esteves, Yousuke Utsumi, Adam Snyder, Theo Schutt, Alex Broughton | Summary: The Vera C. Rubin Observatory’s LSST Camera pixel response has been characterized using laboratory measurements with a grid of artificial stars. We quantify the contributions to photometry, centroid, point-spread function size, and shape measurement […]

Cosmological Distance Measurement of 12 Nearby Supernovae IIP with ROTSE-IIIB

Kavli Affiliate: Eli Rykoff | First 5 Authors: Govinda Dhungana, Robert Kehoe, Ryan Staten, Jozsef Vinko, J. Craig Wheeler | Summary: We present cosmological analysis of 12 nearby ($z<0.06$) Type IIP supernovae (SNe IIP) observed with the ROTSE-IIIb telescope. To achieve precise photometry, we present a new image differencing technique that is implemented for the […]

A search for new physics in low-energy electron recoils from the first LZ exposure

Kavli Affiliate: C. M. Ignarra | First 5 Authors: The LZ Collaboration, J. Aalbers, D. S. Akerib, A. K. Al Musalhi, F. Alder | Summary: The LUX-ZEPLIN (LZ) experiment is a dark matter detector centered on a dual-phase xenon time projection chamber. We report searches for new physics appearing through few-keV-scale electron recoils, using the […]
