Variability as a predictor for the hard-to-soft state transition in GX 339-4

Kavli Affiliate: Erin Kara | First 5 Authors: Matteo Lucchini, Marina Ten Have, Jingyi Wang, Jeroen Homan, Erin Kara | Summary: During the outbursts of black hole X-ray binaries (BHXRBs), their accretion flows transition through several states. The source luminosity rises in the hard state, dominated by non-thermal emission, before transitioning to the blackbody-dominated soft […]

An end-to-end calibration of the Mini-EUSO detector in space

Kavli Affiliate: Angela Olinto | First 5 Authors: Hiroko Miyamoto, Matteo Battisti, Dario Barghini, Alexander Belov, Mario Bertaina | Summary: Mini-EUSO is a wide Field-of-View (FoV, 44$^{circ}$) telescope currently in operation from a nadia-facing UV-transparent window in the Russian Zvezda module on the International Space Station (ISS). It is the first detector of the JEM-EUSO […]

Lyman Continuum Emission from Spectroscopically Confirmed Ly$α$ Emitters at $zsim3.1$

Kavli Affiliate: Linhua Jiang | First 5 Authors: , , , , | Summary: We present a study of Lyman continuum (LyC) emission in a sample of $sim$150 Ly$alpha$ emitters (LAEs) at $zapprox3.1$ in the Subaru-XMM Deep Survey field. These LAEs were previously selected using the narrowband technique and spectroscopically confirmed with Ly$alpha$ equivalent widths […]

The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES): driving science cases and expected outcomes

Kavli Affiliate: Bruce Macintosh | First 5 Authors: , , , , | Summary: The Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES) is a $2-5~mu$m, high-contrast integral field spectrograph (IFS) currently being built for Keck Observatory. With both low ($Rlesssim250$) and medium ($Rsim3500-7000$) spectral resolution IFS modes, SCALES will detect and characterize […]

The classical field approximation of ultra light dark matter: quantum breaktimes, corrections, and decoherence

Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Alvaro Zamora, Michael Kopp, Tom Abel, | Summary: The classical field approximation is widely used to better understand the predictions of ultra-light dark matter. Here, we use the truncated Wigner approximation method to test the classical field approximation of ultra-light dark matter. This method approximates […]

The look of high-velocity red-giant star collisions

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Luc Dessart, Taeho Ryu, Pau Amaro Seoane, Andrew M. Taylor, | Summary: High-velocity stellar collisions driven by a supermassive black hole (BH) or BH-driven disruptive collisions, in dense, nuclear clusters can rival the energetics of supergiant star explosions following gravitational collapse of their iron core. Here, […]
