Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Mason Ng, Paul S. Ray, Peter Bult, Deepto Chakrabarty, Gaurava K. Jaisawal | Summary: We report the detection of 376.05 Hz (2.66 ms) coherent X-ray pulsations in NICER observations of a transient outburst of the low-mass X-ray binary IGR J17494-3030 in 2020 October/November. The system is an […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Jamila Pegues, Ian Czekala, Sean M. Andrews, Karin I. Öberg, Gregory J. Herczeg | Summary: In this era of Gaia and ALMA, dynamical stellar mass measurements provide benchmarks that are independent of observations of stellar characteristics and their uncertainties. These benchmarks can then be used to […]
Kavli Affiliate: Lee McCuller | First 5 Authors: Aidan F. Brooks, Gabriele Vajente, Hiro Yamamoto, Rich Abbott, Carl Adams | Summary: Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nano-meter scale thermo-elastic deformations and substrate lenses from these micron-scale absorbers significantly reduces the […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Xuhao Wu, Shishao Bao, Hong Shen, Renxin Xu, | Summary: The secondary component of GW190814 with a mass of 2.50-2.67 $M_{odot}$ may be the lightest black hole or the heaviest neutron star ever observed in a binary compact object system. To explore the possible equation of state […]
Kavli Affiliate: Keith L. Thompson | First 5 Authors: Benjamin Westbrook, Christopher Raum, Shawn Beckman, Adrian T. Lee, Nicole Farias | Summary: LiteBIRD is a JAXA-led strategic Large-Class satellite mission designed to measure the polarization of the cosmic microwave background and cosmic foregrounds from 34 to 448 GHz across the entire sky from L2 in […]
Kavli Affiliate: Ronald Remillard | First 5 Authors: Thomas Wevers, Dheeraj R. Pasham, Sjoert van Velzen, James C. A. Miller-Jones, Phil Uttley | Summary: Following a tidal disruption event (TDE), the accretion rate can evolve from quiescent to near-Eddington levels and back over months – years timescales. This provides a unique opportunity to study the […]

Kavli Affiliate: David A. Muller | First 5 Authors: Yu-Tsun Shao, Sujit Das, Zijian Hong, Ruijuan Xu, Swathi Chandrika | Summary: Polar skyrmions are predicted to emerge from the interplay of elastic, electrostatic and gradient energies, in contrast to the key role of the anti-symmetric Dzyalozhinskii-Moriya interaction in magnetic skyrmions. With the discovery of topologically-stable […]
Kavli Affiliate: David Muller | First 5 Authors: David Müller, Yurii Nesterov, Vladimir Shikhman, , | Summary: Recently, there is growing interest and need for dynamic pricing algorithms, especially, in the field of online marketplaces by offering smart pricing options for big online stores. We present an approach to adjust prices based on the observed […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Brian P. Powell, Veselin B. Kostov, Saul A. Rappaport, Tamas Borkovits, Petr Zasche | Summary: We report the discovery of a sextuply-eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three eclipsing binaries. The […]
