Kavli Affiliate: Eli S. Rykoff | First 5 Authors: Yuanyuan Zhang, Jesse B. Golden-Marx, Ricardo L. C. Ogando, Brian Yanny, Eli S. Rykoff | Summary: Using the full six years of imaging data from the Dark Energy Survey, we study the surface brightness profiles of galaxy cluster central galaxies and intra-cluster light. We apply a […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: Z. Pan, F. Bianchini, W. L. K. Wu, P. A. R. Ade, Z. Ahmed | Summary: We present a measurement of gravitational lensing over 1500 deg$^2$ of the Southern sky using SPT-3G temperature data at 95 and 150 GHz taken in 2018. The lensing amplitude relative to […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Philip Mansfield, Elise Darragh-Ford, Yunchong Wang, Ethan O. Nadler, Risa H. Wechsler | Summary: A major question in $Lambda$CDM is what this theory actually predicts for the properties of subhalo populations. Subhalos are difficult to simulate and to find within simulations, and this propagates into uncertainty […]
Kavli Affiliate: Risa Wechsler | Summary:A major question in $Λ$CDM is what this theory actually predicts for the properties of subhalo populations. Subhalos are difficult to simulate and to find within simulations, and this propagates into uncertainty in theoretical predictions for satellite galaxies. We present Symfind, a new particle-tracking-based subhalo finder, and demonstrate that it […]
Kavli Affiliate: 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 the primary particles are still unknown. Individual EECRs sources become more prominent, […]
Kavli Affiliate: Grzegorz Madejski | 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 by, e.g., Suzaku, and now NuSTAR, have not been able to confirm these detections. We report […]
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 (LSSTCam) 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 […]

Kavli Affiliate: Aaron Roodman | Summary:The Vera C. Rubin Observatory’s LSST Camera (LSSTCam) 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 errors due to small anomalies in the LSSTCam CCDs. The main sources of those anomalies […]
