X-Ray Polarimetry of the Dipping Accreting Neutron Star 4U 1624-49

Kavli Affiliate: Herman L. Marshall | First 5 Authors: M. Lynne Saade, Philip Kaaret, Andrea Gnarini, Juri Poutanen, Francesco Ursini | Summary: We present the first X-ray polarimetric study of the dipping accreting neutron star 4U 1624$-$49 with the Imaging X-ray Polarimetry Explorer (IXPE). We report a detection of polarization in the non-dip time intervals […]

Evidence for a dynamic corona in the short-term time lags of black hole X-ray binary MAXI J1820+070

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Niek Bollemeijer, Phil Uttley, Arkadip Basak, Adam Ingram, Jakob van den Eijnden | Summary: In X-ray observations of hard state black hole X-ray binaries, rapid variations in accretion disc and coronal power-law emission are correlated and show Fourier-frequency-dependent time lags. On short (~0.1 s) time-scales, these […]

matvis: A matrix-based visibility simulator for fast forward modelling of many-element 21 cm arrays

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Piyanat Kittiwisit, Steven G. Murray, Hugh Garsden, Philip Bull, Christopher Cain | Summary: Detection of the faint 21 cm line emission from the Cosmic Dawn and Epoch of Reionisation will require not only exquisite control over instrumental calibration and systematics to achieve the necessary dynamic range […]

DEATHSTAR: A system for confirming planets and identifying false positive signals in TESS data using ground-based time domain surveys

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Gabrielle Ross, Andrew Vanderburg, Zoë L. de Beurs, Karen A. Collins, Rob J. Siverd | Summary: We present a technique for verifying or refuting exoplanet candidates from the Transiting Exoplanet Survey Satellite (TESS) mission by searching for nearby eclipsing binary stars using higher-resolution archival images from ground-based […]

ZWCL 1856.8 : A rare double radio relic system captured within NuSTAR and Chandra field of view

Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Ayşegül Tümer, Daniel R. Wik, Gerrit Schellenberger, Eric D. Miller, Marshall W. Bautz | Summary: Observations of galaxy cluster mergers provide insights on the particle acceleration and heating mechanisms taking place within the intracluster medium. Mergers form shocks that propagate through the plasma, which result in […]
