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 […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Amer Aljanabi, Mohanad Abd Shehab, Osama Alluhaibi, Qasim Zeeshan Ahmed, Pavlos Lazaridis | Summary: The problem of underwater acoustic (UWA) channel estimation is the non-uniform sparse representation that may increase the algorithm complexity and the required time. A mathematical framework utilizing l21 constraint with two-dimensional frequency domain […]
Kavli Affiliate: Eli S. Rykoff | First 5 Authors: Hiroaki Aihara, Yusra AlSayyad, Makoto Ando, Robert Armstrong, James Bosch | Summary: The paper presents the third data release of Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), a wide-field multi-band imaging survey with the Subaru 8.2m telescope. HSC-SSP has three survey layers (Wide, Deep, and UltraDeep) with […]
