Kavli Affiliate: Nicola Omodei | First 5 Authors: Melissa Pesce-Rollins, Nicola Omodei, Vahe’ Petrosian, Francesco Longo, | Summary: High-energy solar flares have shown to have at least two distinct phases: prompt-impulsive and delayed-gradual. Identifying the mechanism responsible for accelerating the electrons and ions and the site at which it occurs during these two phases is […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Arka Banerjee, Susmita Adhikari, Yao-Yuan Mao, Risa H. Wechsler | Summary: Given recent developments in our understanding of the Large Magellanic Cloud’s (LMC) impact on the Milky Way’s (MW) dark matter subhalo population, we compare the signatures of dark matter and baryonic physics […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration, R. Abbott, T. D. Abbott | Summary: Results are presented of searches for continuous gravitational waves from 20 accreting millisecond X-ray pulsars with accurately measured spin frequencies and orbital parameters, using data from the third observing run […]
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, […]
