Kavli Affiliate: Claudio Ricci | First 5 Authors: Hyunsung D. Jun, Roberto J. Assef, Christopher M. Carroll, Ryan C. Hickox, Yonghwi Kim | Summary: The absence of high Eddington ratio, obscured Active Galactic Nuclei (AGN) in local ($zlesssim0.1$) samples of moderate luminosity AGN has generally been explained to result from radiation pressure on the dusty […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Steve Bryson, Michelle Kunimoto, Ravi K. Kopparapu, Jeffrey L. Coughlin, William J. Borucki | Summary: We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties. We provide the […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Thibaut Louis, Sigurd Naess, Xavier Garrido, Anthony Challinor, | Summary: We present a simple approximation that can speed up the computation of the mode-coupling matrices, which are usually the bottleneck for computing unbiased angular power spectra, as well as their associated covariance matrices, of the cosmic microwave […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Antón Baleato Lizancos, Anthony Challinor, Julien Carron, , | Summary: Efforts to detect a primordial $B$-mode of CMB polarization generated by inflationary gravitational waves ought to mitigate the large variance associated with the $B$-modes produced by gravitational lensing, a process known as delensing. A popular approach to […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Sebastian Wagner-Carena, Ji Won Park, Simon Birrer, Philip J. Marshall, Aaron Roodman | Summary: In the past few years, approximate Bayesian Neural Networks (BNNs) have demonstrated the ability to produce statistically consistent posteriors on a wide range of inference problems at unprecedented speed and scale. However, […]
Kavli Affiliate: Mihoko M. Nojiri | First 5 Authors: Sung Hak Lim, Mihoko M. Nojiri, , , | Summary: We introduce a jet tagger based on a neural network analyzing the Minkowski Functionals (MFs) of pixellated jet images. The MFs are geometric measures of binary images, and they can be regarded as a generalization of […]
Kavli Affiliate: Andrei Okounkov | First 5 Authors: Andrei Okounkov, , , , | Summary: We generalize the construction of elliptic stable envelopes to actions of connected reductive groups and give a direct inductive proof of their existence and uniqueness in a rather general situation. We show these have powerful enumerative applications, in particular, to […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Ian J. M. Crossfield, Diana Dragomir, Nicolas B. Cowan, Tansu Daylan, Ian Wong | Summary: Phase curve measurements provide a global view of the composition, thermal structure, and dynamics of exoplanet atmospheres. Although most of the dozens of phase curve measurements made to date are of […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Erin Boettcher, Hsiao-Wen Chen, Fakhri S. Zahedy, Thomas J. Cooper, Sean D. Johnson | Summary: We report the serendipitous detection of an H$_{2}$-bearing damped Lyman-$alpha$ absorber at z = 0.576 in the spectrum of the QSO J0111-0316 in the Cosmic Ultraviolet Baryon Survey. Spectroscopic observations from […]
Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Matthew Dodelson, Hirosi Ooguri, , , | Summary: We analyze the singularities of the two-point function in a conformal field theory at finite temperature. In a free theory, the only singularity is along the boundary light cone. In the holographic limit, a new class of singularities emerges […]
