Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Justin M. Wittrock, Stefan Dreizler, Michael A. Reefe, Brett M. Morris, Peter P. Plavchan | Summary: We explore the transit timing variations (TTVs) of the young (22 Myr) nearby AU Mic planetary system. For AU Mic b, we introduce three Spitzer (4.5 $mu$m) transits, five TESS transits, […]

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Veselin B. Kostov, Brian P. Powell, Saul A. Rappaport, Tamas Borkovits, Robert Gagliano | Summary: We present a catalog of 97 uniformly-vetted candidates for quadruple star systems. The candidates were identified in TESS Full Frame Image data from Sectors 1 through 42 through a combination of machine […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Carolina Andonie, Claudio Ricci, Stéphane Paltani, Patricia Arévalo, Ezequiel Treister | Summary: Reprocessed X-ray emission in Active Galactic Nuclei (AGN) can provide fundamental information about the circumnuclear environments of supermassive black holes. Recent mid-infrared studies have shown evidence of an extended dusty structure perpendicular to the torus […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Sung-Yong Yoon, Gregory J. Herczeg, Jeong-Eun Lee, Ho-Gyu Lee, Doug Johnstone | Summary: Observed changes in protostellar brightness can be complicated to interpret. In our JCMT~Transient monitoring survey, we discovered that a young binary protostar, HOPS 373, is undergoing a modest $30%$ brightness increase at 850 […]
Kavli Affiliate: Michael Shadlen | Authors: Naomi N Odean, Mehdi Sanayei and Michael N Shadlen | Summary: Abstract To form a perceptual decision the brain must acquire samples of evidence from the environment and incorporate them in computations that mediate choice behavior. While much is known about the neural circuits that process sensory information and […]
Kavli Affiliate: R. Morris | First 5 Authors: Jun-Hui Zhao, Mark R. Morris, W. M. Goss, , | Summary: Using the JVLA, we explored the Galactic center (GC) with a resolution of 0.05" at 33.0 and 44.6 GHz. We detected 64 hyper-compact radio sources (HCRs) in the central parsec. The dense group of HCRs can […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Hui Sun, He-Yang Liu, Haiwu Pan, Zhu Liu, Dennis Alp | Summary: A dozen X-ray supernova shock breakout (SN SBO) candidates were reported recently based on XMM-Newton archival data, which increased the X-ray selected SN SBO sample by an order of magnitude. Assuming they are genuine SN […]
Kavli Affiliate: Catherine E. Grant | First 5 Authors: Fabio Gastaldello, Martino Marelli, Silvano Molendi, Iacopo Bartalucci, Patrick Kühl | Summary: We analyzed the unexposed to the sky outFOV region of the MOS2 detector on board XMM-Newton covering 15 years of data amounting to 255 Ms. We show convincing evidence that the origin of the […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stephanie O’Neil, Josh Borrow, Mark Vogelsberger, Benedikt Diemer, | Summary: We explore how the splashback radius ($R_{rm sp}$) of galaxy clusters, measured using the number density of the subhalo population, changes based on various selection criteria using the IllustrisTNG cosmological galaxy formation simulation. We identify $R_{rm sp}$ […]
