Kavli Affiliate: Nicola Omodei | 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 with […]
Kavli Affiliate: Tom Abel | First 5 Authors: Karsten Jedamzik, Tom Abel, , , | Summary: Primordial magnetic fields (PMFs) may explain observations of magnetic fields on extragalactic scales. They are most cleanly constrained by observations of details of the cosmic microwave background radiation (CMB) Their effects on cosmic recombination may even be at the […]
Kavli Affiliate: Tom Abel | First 5 Authors: Karsten Jedamzik, Tom Abel, Yacine Ali-Haimoud, , | Summary: Primordial magnetic fields (PMFs) may explain observations of magnetic fields on extragalactic scales. They are most cleanly constrained by measurements of cosmic microwave background radiation (CMB) anisotropies. Their effects on cosmic recombination may even be at the heart […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Tirth Surti, Roger W. Romani, Julia Scharwächter, Alison Peck, Greg B. Taylor | Summary: We report on IFU measurements of the host of the radio source 4C+37.11. This massive elliptical contains the only resolved double compact nucleus at pc-scale separation, likely a bound supermassive black hole […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Noah Glennon, Nathan Musoke, Ethan O. Nadler, Chanda Prescod-Weinstein, Risa H. Wechsler | Summary: We explore how dynamical friction in an ultralight dark matter (ULDM) background is affected by dark matter self-interactions. We calculate the force of dynamical friction on a point mass moving through a […]
Kavli Affiliate: Richard Dubois | First 5 Authors: Edward Karavakis, Wen Guan, Zhaoyu Yang, Tadashi Maeno, Torre Wenaus | Summary: The Vera C. Rubin Observatory will produce an unprecedented astronomical data set for studies of the deep and dynamic universe. Its Legacy Survey of Space and Time (LSST) will image the entire southern sky every […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Simon Petrus, Niall Whiteford, Polychronis Patapis, Beth A. Biller, Andrew Skemer | Summary: The unprecedented medium-resolution (R=1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (120-160Myr) low-mass (12-20MJup) L-T transition (L7) companion VHS1256b has opened new avenues for the in-depth characterization of substellar object […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Simon Petrus, Niall Whiteford, Polychronis Patapis, Beth A. Biller, Andrew Skemer | Summary: The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) companion VHS1256b gives access to a catalogue of molecular absorptions. In this study, […]
Kavli Affiliate: Stuart Marshall | First 5 Authors: Alex Broughton, Yousuke Utsumi, Andrés Plazas Malagón, Christopher Waters, Craig Lage | Summary: Thick, fully depleted charge-coupled devices (CCDs) are known to exhibit non-linear behavior at high signal levels due to the dynamic behavior of charges collecting in the potential wells of pixels, called the brighter-fatter effect […]
