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 […]

Kavli Affiliate: Erin A. Kara | First 5 Authors: Y. Homayouni, Gerard A. Kriss, Gisella De Rosa, Rachel Plesha, Edward M. Cackett | Summary: An intensive reverberation mapping campaign on the Seyfert 1 galaxy Mrk817 using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) revealed significant variations in the response of the […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Riccardo Middei, Matteo Perri, Simonetta Puccetti, Ioannis Liodakis, Laura Di Gesu | Summary: The lower energy peak of the spectral energy distribution of blazars has commonly been ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consensus regarding jet emission processes, the particle […]
