Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Ana Belén Griñón-Marín, Adur Pastor Yabar, Yang Liu, J. Todd Hoeksema, Aimee Norton | Summary: A spectral line inversion code, Very Fast Inversion of the Stokes Vector (VFISV), has been used since May 2010 to infer the solar atmospheric parameters from the spectropolarimetric observations taken by […]
Kavli Affiliate: Roger D. Blandford | First 5 Authors: Noemie Globus, Roger D. Blandford, Anatoli Fedynitch, , | Summary: While biologists have not yet reached a consensus on the definition of life, homochirality – the specific molecular handedness of biomolecules – is a phenomenon only produced by life. The unraveling of its origin requires interdisciplinary […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Jean-Baptiste Ruffio, Quinn M. Konopacky, Travis Barman, Bruce Macintosh, Kielan K. Wilcomb | Summary: The four directly imaged planets orbiting the star HR 8799 are an ideal laboratory to probe atmospheric physics and formation models. We present more than a decade’s worth of Keck/OSIRIS observations of these […]
Kavli Affiliate: Tom Abel | First 5 Authors: Lehman H. Garrison, Tom Abel, Daniel J. Eisenstein, , | Summary: We use the $k$-nearest neighbor probability distribution function ($k$NN-PDF, Banerjee & Abel 2021) to assess convergence in a scale-free $N$-body simulation. Compared to our previous two-point analysis, the $k$NN-PDF allows us to quantify our results in […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Milena Crnogorčević, Regina Caputo, Manuel Meyer, Nicola Omodei, Michael Gustafsson | Summary: Light axion-like particles (ALPs) are expected to be abundantly produced in core-collapse supernovae (CCSNe), resulting in a $sim$10-second long burst of ALPs. These particles subsequently undergo conversion into gamma-rays in external magnetic fields to produce […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Yonit Hochberg, Eric David Kramer, Noah Kurinsky, Benjamin V. Lehmann, | Summary: Superconducting detectors have been proposed as outstanding targets for the direct detection of light dark matter scattering at masses as low as a keV. We study the prospects for directional detection of dark matter in […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Giacomo Principe, Nicola Omodei, Niccolò Di Lalla, Leonardo Di Venere, Francesco Longo | Summary: Fast radio bursts (FRBs) are one of the most exciting new mysteries of astrophysics. Their origin is still unknown, but recent observations seems to link them to Soft Gamma Repeaters and, in particular, […]
Kavli Affiliate: Peter F. Michelson | First 5 Authors: Pei Wang, Di Li, Colin J. Clark, Pablo Saz Parkinson, Xian Hou | Summary: High sensitivity radio searches of unassociated $gamma$-ray sources have proven to be an effective way of finding new pulsars. Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) during its commissioning phase, we […]

Kavli Affiliate: Eric Charles | First 5 Authors: Celine Armand, Eric Charles, Mattia di Mauro, Chiara Giuri, J. Patrick Harding | Summary: Cosmological and astrophysical observations suggest that 85% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challenging and fundamental open questions […]
