Kavli Affiliate: Catherine E. Grant | First 5 Authors: Eric D. Miller, James A. Gregory, Marshall W. Bautz, Harry R. Clark, Michael Cooper | Summary: Future X-ray astrophysics missions will survey large areas of the sky with unparalleled sensitivity, enabled by lightweight, high-resolution optics. These optics inherently produce curved focal surfaces with radii as small […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Sydney Jenkins, Andrew Vanderburg, Allyson Bieryla, David W. Latham, Mariona Badenas-Agusti | Summary: Over a quarter of white dwarfs have photospheric metal pollution, which is evidence for recent accretion of exoplanetary material. While a wide range of mechanisms have been proposed to account for this pollution, there […]
Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Dheeraj Pasham, Eric Coughlin, Muryel Guolo, Thomas Wevers, Chris Nixon | Summary: The tidal disruption event (TDE) AT2018dyk/ASASSN-18UL showed a rapid dimming event 500 days after discovery, followed by a re-brightening roughly 700 days later. It has been hypothesized that this behavior results from a repeating partial […]
Kavli Affiliate: Erin Kara | First 5 Authors: Eileen T. Meyer, Sibasish Laha, Onic I. Shuvo, Agniva Roychowdhury, David A. Green | Summary: We present multi-frequency (5-345 GHz) and multi-resolution radio observations of 1ES 1927+654, widely considered one of the most unusual and extreme changing-look active galactic nuclei (CL-AGN). The source was first designated a […]

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Venu M. Kalari, Ricardo Salinas, Hans Zinnecker, Monica Rubio, Gregory Herczeg | Summary: Constraints on the binary fraction of young massive stellar objects (mYSOs) are important for binary and massive star formation theory. Here, we present speckle imaging of 34 mYSOs located in the Large (1/2 $Z_{odot}$) […]
Kavli Affiliate: Erin Kara | First 5 Authors: Chris John, Kishalay De, Matteo Lucchini, Ehud Behar, Erin Kara | Summary: The mid-infrared (MIR; $lambdasimeq3 – 10mu$m) bands offer a unique window into understanding accretion and its interplay with jet formation in Galactic black hole X-ray binaries (BHXRBs). Although extremely difficult to observe from the ground, […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Matthew Colless, Arjen van der Wel, Sam P. Vaughan, Khaled Said | Summary: We use deep spectroscopy from the SAMI Galaxy Survey to explore the precision of the fundamental plane of early-type galaxies (FP) as a distance indicator for future single-fibre spectroscopy surveys. We study […]
Kavli Affiliate: Bradford A. Benson | First 5 Authors: Cesiley L. King, Ian Gullet, Adam J. Anderson, Bradford A. Benson, Rick Bihary | Summary: We present the design and validation of a variable temperature cryogenic blackbody source, hereinafter called a cold load, that will be used to characterize detectors to be deployed by CMB-S4, the […]
