Kavli Affiliate: Rainer Weiss | First 5 Authors: D. H. Shoemaker, Stefan Ballmer, Matteo Barsuglia, E. Berger, Emanuele Berti | Summary: The workshop Dawn VI: Next Generation Observatories took place online over three days, 5-7 October, 2021. More than 200 physicists and astronomers attended to contribute to, and learn from, a discussion of next-generation ground-based […]
Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Janusz J. Petkowski, Paul B. Rimmer, Sara Seager, | Summary: The atmosphere of Venus remains mysterious, with many outstanding chemical connundra. These include: the unexpected presence of ~10 ppm O2 in the cloud layers; an unknown composition of large particles in the lower cloud layers; […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Minjung Park, Sandro Tacchella, Erica J. Nelson, Lars Hernquist, Rainer Weinberger | Summary: Observations have shown that the star-formation activity and the morphology of galaxies are closely related, but the underlying physical connection is not well understood. Using the TNG50 simulation, we explore the quenching and the […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Rahul Jayaraman, Swetlana Hubrig, Daniel L. Holdsworth, Markus Schöller, Silva Järvinen | Summary: We report the detection and characterization of a new magnetospheric star, HD 135348, based on photometric and spectropolarimetric observations. The TESS light curve of this star exhibited variations consistent with stars known to […]
Kavli Affiliate: David A. Principe | First 5 Authors: Steven M. Silverberg, Hans Moritz Guenther, Jinyoung Serena Kim, David A. Principe, Scott J. Wolk | Summary: Empirically, the estimated lifetime of a typical protoplanetary disk is $<5-10$ Myr. However, the disk lifetimes required to produce a variety of observed exoplanetary systems may exceed this timescale. […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: Handedness, or chirality, has been a continuing source of inspiration across a wide range of scientific problems. After a quick review of some important, instructive historical examples, I present three contemporary case studies involving sophisticated applications of chirality at the […]
Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Janusz J. Petkowski, Christopher E. Carr, David Grinspoon, Bethany Ehlmann | Summary: The Venus Life Finder Missions are a series of focused astrobiology mission concepts to search for habitability, signs of life, and life itself in the Venus atmosphere. While people have speculated on life […]
Kavli Affiliate: Marshall Bautz | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Barry Burke, Kevan Donlon, Gregory Prigozhin | Summary: We present an evaluation of a novel on-chip charge detector, called the Single electron Sensitive Read Out (SiSeRO), for charge-coupled device (CCD) image sensor applications. It uses a p-MOSFET transistor at the output stage with […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Wynn C. G. Ho, William Alston, Ronald Remillard, Mason Ng | Summary: The brightest Fast Blue Optical Transients (FBOTs) are mysterious extragalactic explosions that may represent a new class of astrophysical phenomena. Their fast time to maximum brightness of less than a week […]
