An Exceptionally Powerful, Radiatively Driven Ultrafast Outflow in the Rapidly Accreting AGN REJ1034+396

Kavli Affiliate: Steven Allen | First 5 Authors: Chloe Taylor, Daniel Wilkins, Steven Allen, , | Summary: We report the analysis of ~1Ms of XMM-Newton observations of the rapidly accreting active galactic nucleus REJ1034+396. The 0.3-9 keV EPIC-pn spectra are well described by a model consisting of steep continuum emission from the corona accompanied by […]

A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star

Kavli Affiliate: Sara Seager | First 5 Authors: Marc Hon, Saul Rappaport, Avi Shporer, Andrew Vanderburg, Karen A. Collins | Summary: We report the discovery of BD+05$,$4868$,$Ab, a transiting exoplanet orbiting a bright ($V=10.16$) K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) reveal variable transit depths […]

Rigorous analytic solution to the gravitational-wave overlapping event rates

Kavli Affiliate: Lijing Shao | First 5 Authors: Ziming Wang, Zexin Hu, Lijing Shao, , | Summary: In the era of the next-generation gravitational-wave detectors, signal overlaps will become prevalent due to high detection rate and long signal duration, posing significant challenges to data analysis. While effective algorithms are being developed, there still lacks an […]

The impact of the redshift-dependent selection effect of halos on the redshift-space power spectrum

Kavli Affiliate: Masahiro Takada | First 5 Authors: Kanmi Nose, Masahiro Takada, Ryo Terasawa, , | Summary: In a wide-area spectroscopic survey of galaxies, it is nearly impossible to obtain a homogeneous sample of galaxies with respect to galaxy properties such as stellar mass and host halo mass across a range of redshifts. Despite the […]

Non-Markovian Noise Mitigation: Practical Implementation, Error Analysis, and the Role of Environment Spectral Properties

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Xiantao Li, , , | Summary: Quantum error mitigation (QEM), conceived as an error suppression paradigm without the need for additional ancilla qubits for noisy intermediate-scale quantum (NISQ) devices, presents a promising avenue for realizing quantum speedups of quantum computing algorithms on current quantum devices. […]

How to Minimize the Decoherence Caused by Black Holes

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Jonah Kudler-Flam, Gautam Satishchandran, Robert M. Wald, | Summary: We consider an experimentalist, Alice, who creates a quantum superposition of a charged or massive body outside of a black hole (or, more generally, in the presence of a Killing horizon). It was previously […]
