Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Monica Valluri, Parker Fagrelius, Sergey. E. Koposov, Ting S. Li, Oleg Y. Gnedin | Summary: We present ~ 126 new spectroscopically identified members of the GD-1 tidal stream obtained with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence of a “cocoon” which is […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Monica Valluri, Parker Fagrelius, Sergey. E. Koposov, Ting S. Li, Oleg Y. Gnedin | Summary: We present 115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence of a “cocoon” which is a […]
Kavli Affiliate: Eli Rykoff | First 5 Authors: Robert Armstrong, Erin Sheldon, Eric Huff, Jim Bosch, Eli Rykoff | Summary: Upcoming wide field surveys will have many overlapping epochs of the same region of sky. The conventional wisdom is that in order to reduce the errors sufficiently for systematics-limited measurements, like weak lensing, we must […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Matthew A. Petroff, Zeeshan Ahmed, James J. Bock, Marion Dierickx, Sofia Fatigoni | Summary: The search for the polarized imprint of primordial gravitational waves in the cosmic microwave background (CMB) as direct evidence of cosmic inflation requires exquisite sensitivity and control over systematics. The next-generation CMB-S4 project […]

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Chao Liu, Zeeshan Ahmed, Shawn W. Henderson, Ryan Herbst, Larry Ruckman | Summary: The SLAC Microresonator Radio Frequency (SMuRF) electronics is being deployed as the readout for the Cosmic Microwave Background (CMB) telescopes of the Simons Observatory (SO). A Radio Frequency System-on-Chip (RFSoC) based readout of microwave […]
Kavli Affiliate: Steven W. Allen | First 5 Authors: Maya Benyas, Jordan Pfeifer, Adam B. Mantz, Steven W. Allen, Elise Darragh-Ford | Summary: The X-ray morphologies of clusters of galaxies display significant variations, reflecting their dynamical histories and the nonlinear dependence of X-ray emissivity on the density of the intracluster gas. Qualitative and quantitative assessments […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Sofia V. Forsblom, Sergey S. Tsygankov, Juri Poutanen, Victor Doroshenko, Alexander A. Mushtukov | Summary: Recent observations of X-ray pulsars (XRPs) performed by the Imaging X-ray Polarimetry Explorer (IXPE) have made it possible to investigate the intricate details of these objects in a new way, thanks to […]
Kavli Affiliate: Stuart Marshall | First 5 Authors: Sara I. Walker, Cole Mathis, Stuart Marshall, Leroy Cronin, | Summary: Assembly Theory (AT) was developed to help distinguish living from non-living systems. The theory is simple as it posits that the amount of selection or Assembly is a function of the number of complex objects where […]
Kavli Affiliate: Robert Cameron | First 5 Authors: Heike Rauer, Conny Aerts, Juan Cabrera, Magali Deleuil, Anders Erikson | Summary: PLATO (PLAnetary Transits and Oscillations of stars) is ESA’s M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large number of stars. PLATO will detect small planets (down to […]
