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 […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: L. Balkenhol, D. Dutcher, A. Spurio Mancini, A. Doussot, K. Benabed | Summary: We present a sample-variance-limited measurement of the temperature power spectrum ($TT$) of the cosmic microwave background (CMB) using observations of a $sim! 1500 ,mathrm{deg}^2$ field made by SPT-3G in 2018. We report multifrequency power […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Kielan K. W. Hoch, Quinn M. Konopacky, Christopher A. Theissen, Jean-Baptiste Ruffio, Travis S. Barman | Summary: The carbon-to-oxygen (C/O) ratio in an exoplanet atmosphere has been suggested as a potential diagnostic of planet formation. Now that a number of exoplanets have measured C/O ratios, it is […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Christian Boyd, Yonit Hochberg, Yonatan Kahn, Eric David Kramer, Noah Kurinsky | Summary: Direct detection for sub-GeV dark matter is developing rapidly, with many novel experimental ideas and theoretical methods emerging. In this work, we extend the dielectric formalism for dark matter scattering to incorporate anisotropic material […]

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Adam J. Fleisher, Zeeshan Ahmed, Tobias Herman, Matthew R. Hartings, | Summary: We report a precision realization of photonic thermometry using dual-comb spectroscopy to interrogate a $pi$-phase-shifted fiber Bragg grating. We achieve read-out stability of 7.5 mK at 1 s and resolve temperature changes of similar magnitude–sufficient […]
