Kavli Affiliate: Erin Kara | First 5 Authors: Dheeraj R. Pasham, Francesco Tombesi, Petra Sukova, Michal Zajacek, Suvendu Rakshit | Summary: Binaries containing a compact object orbiting a supermassive black hole are thought to be precursors of gravitational wave events, but their identification has been extremely challenging. Here, we report quasi-periodic variability in X-ray absorption […]

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Eric R. Coughlin, Michal Zajacek, Itai Linial, Petra Sukova | Summary: Quasi-periodic Eruptions (QPEs) represent a novel class of extragalactic X-ray transients that are known to repeat at roughly regular intervals of a few hours to days. Their underlying physical mechanism is a […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Michal Zajacek, C. J. Nixon, Eric R. Coughlin, Marzena Sniegowska | Summary: An accretion disk formed around a supermassive black hole (SMBH) after it disrupts a star is expected to be initially misaligned with respect to the black hole’s equatorial plane. This misalignment […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Junna Sugiyama, Tomoki Terasaki, Kana Sakaguri, Bryce Bixler, Yuki Sakurai | Summary: The Simons Observatory (SO) experiment is a cosmic microwave background (CMB) experiment located in the Atacama Desert, Chile. The SO’ s small aperture telescopes (SATs) consist of three telescopes designed for precise CMB polarimetry at […]

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ryan Mckinven, Mohit Bhardwaj, Tarraneh Eftekhari, Charles D. Kilpatrick, Aida Kirichenko | Summary: Fast radio bursts (FRBs) last for milliseconds and arrive at Earth from cosmological distances. While their origin(s) and emission mechanism(s) are presently unknown, their signals bear similarities with the much less luminous radio […]
Kavli Affiliate: C. M. Ignarra | First 5 Authors: J. Aalbers, D. S. Akerib, A. K. Al Musalhi, C. S. Amarasinghe, A. Ames | Summary: Searches for dark matter with liquid xenon time projection chamber experiments have traditionally focused on the region of the parameter space that is characteristic of weakly interacting massive particles, ranging […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Martin Millon, Kevin Michalewicz, Frédéric Dux, Frédéric Courbin, Philip J. Marshall | Summary: We present STARRED, a Point Spread Function (PSF) reconstruction, two-channel deconvolution, and light curve extraction method designed for high-precision photometric measurements in imaging time series. An improved resolution of the data is targeted […]
