Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Sjoert van Velzen, Dheeraj R. Pasham, Stefanie Komossa, Lin Yan, Erin A. Kara | Summary: Stellar tidal disruption events (TDEs) are typically discovered by transient emission due to accretion or shocks of the stellar debris. Yet this luminous flare can be reprocessed by gas or dust […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Herman L. Marshall, , , , | Summary: For a track based polarimeter, such as the Imaging X-ray Polarimetry Explorer (IXPE), the sensitivity to polarization depends on the modulation factor, which is a strong function of energy. In previous work, a likelihood method was developed that […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Vijay Varma, Sylvia Biscoveanu, Maximiliano Isi, Will M. Farr, Salvatore Vitale | Summary: Binary black hole spin measurements from gravitational wave observations can reveal the binary’s evolutionary history. In particular, the spin orientations of the component black holes within the orbital plane, $phi_1$ and $phi_2$, can be […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Vijay Varma, Maximiliano Isi, Sylvia Biscoveanu, Will M. Farr, Salvatore Vitale | Summary: Binary black hole spins are among the key observables for gravitational wave astronomy. Among the spin parameters, their orientations within the orbital plane, $phi_1$, $phi_2$ and $Delta phi=phi_1-phi_2$, are critical for understanding the prevalence […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, Bridget C. Andersen, Kevin Bandura, Mohit Bhardwaj, P. J. Boyle | Summary: The origin of fast radio bursts (FRBs), millisecond-duration flashes of radio waves that are visible at distances of billions of light-years, remains an open astrophysical question. Here we report the detection […]
Kavli Affiliate: Erin Kara | First 5 Authors: Guglielmo Mastroserio, Adam Ingram, Jingyi Wang, Javier A. García, Michiel van der Klis | Summary: We present a new release of the RELTRANS model to fit the complex cross-spectrum of accreting black holes as a function of energy. The model accounts for continuum lags and reverberation lags […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ryan Mckinven, Daniele Michilli, Kiyoshi W. Masui, Davor Cubranic, B. M. Gaensler | Summary: Polarimetric observations of Fast Radio Bursts (FRBs) are a powerful resource for better understanding these mysterious sources by directly probing the emission mechanism of the source and the magneto-ionic properties of its […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Nolan Grieves, François Bouchy, Monika Lendl, Theron Carmichael, Ismael Mireles | Summary: We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exoplanet Survey Satellite (TESS) as TESS Objects of Interest […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Hsin-Yu Chen, Salvatore Vitale, Francois Foucart, , | Summary: The origin of the heavy elements in the Universe is not fully determined. Neutron star-black hole (NSBH) and {binary neutron star} (BNS) mergers may both produce heavy elements via rapid neutron-capture (r-process). We use the recent detection of […]
Kavli Affiliate: Saul Rappaport | First 5 Authors: Samuel N. Quinn, Saul Rappaport, Andrew Vanderburg, Jason D. Eastman, Lorne A. Nelson | Summary: We report the detection of a single transit-like signal in the Kepler data of the slightly evolved F star KIC4918810. The transit duration is ~45 hours, and while the orbital period ($Psim10$ […]
