Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Rahul Jayaraman, Michael Fausnaugh, George R. Ricker, Roland Vanderspek, | Summary: Throughout the past three decades, only a few tens of observations have been made of optical flashes contemporaneous with gamma-ray bursts (GRBs), despite the thousands of GRBs that have been detected during that same timeframe. In […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Rahul Jayaraman, Michael Fausnaugh, George R. Ricker, Roland Vanderspek, | Summary: Very few detections have been made of optical flashes contemporaneous with the prompt high-energy emission from a gamma-ray burst (GRB). In this work, we present and analyze light curves of optical GRB flashes and afterglows from […]

Kavli Affiliate: Sara Seager | First 5 Authors: Amaury H. M. J. Triaud, Georgina Dransfield, Taiki Kagetani, Mathilde Timmermans, Norio Narita | Summary: In the last decade, a dozen close-in giant planets have been discovered orbiting stars with spectral types ranging from M0 to M4, a mystery since known formation pathways do not predict the […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Roberto Turolla, Roberto Taverna, Gian Luca Israel, Fabio Muleri, Silvia Zane | Summary: Recent observations with the Imaging X-ray Polarimetry Explorer (IXPE) of two anomalous X-ray pulsars provided evidence that X-ray emission from magnetar sources is strongly polarized. Here we report on the joint IXPE and […]
Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Pragati Pradhan, David P. Huenemoerder, Richard Ignace, Joy S. Nichols, A. M. T. Pollock | Summary: Identifying trends between observational data and the range of physical parameters of massive stars is a critical step to the still-elusive full understanding of the source, structure, and evolution of […]
