AlgoSCR: An algorithm for Solar Contamination Removal from radio interferometric data

Kavli Affiliate: Albert Stebbins | First 5 Authors: Anh Phan, Santanu Das, Albert Stebbins, Peter Timbie, Reza Ansari | Summary: Hydrogen intensity mapping is a new field in astronomy that promises to make three-dimensional maps of the matter distribution of the Universe using the redshifted $21,textrm{cm}$ line of neutral hydrogen gas (HI). Several ongoing and […]

Palatini gravity with nonmetricity, torsion, and boundaries in metric and connection variables

Kavli Affiliate: J. S. Villasenor | First 5 Authors: Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo, Eduardo J. S. Villaseñor, | Summary: We prove the equivalence in the covariant phase space of the metric and connection formulations for Palatini gravity, with nonmetricity and torsion, on a spacetime manifold with boundary. To this end, we will […]

Breaching the limit: formation of GW190521-like and IMBH mergers in young massive clusters

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Manuel Arca Sedda, Francesco Paolo Rizzuto, Thorsten Naab, Jeremiah Ostriker, Mirek Giersz | Summary: The LIGO-Virgo-Kagra collaboration (LVC) discovered recently GW190521, a gravitational wave (GW) source associated with the merger between two black holes (BHs) with mass $66$ M$_odot$ and $>85$ M$_odot$. GW190521 represents the first BH […]

Reverberation mapping of Active Galactic Nuclei: from X-ray corona to dusty torus

Kavli Affiliate: Erin Kara | First 5 Authors: Edward M. Cackett, Misty C. Bentz, Erin Kara, , | Summary: The central engines of Active Galactic Nuclei (AGNs) are powered by accreting supermassive black holes, and while AGNs are known to play an important role in galaxy evolution, the key physical processes occur on scales that […]

Exploring Evaporating Primordial Black Holes with Gravitational Waves

Kavli Affiliate: Misao Sasaki | First 5 Authors: Guillem Domènech, Volodymyr Takhistov, Misao Sasaki, , | Summary: Primordial black holes (PBHs) from the early Universe have been connected with the nature of dark matter and can significantly affect cosmological history. We show that coincidence dark radiation and density fluctuation gravitational wave signatures associated with evaporation […]

Learning Gaussian Graphical Models with Latent Confounders

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Alexander Franks, Sang-Yun Oh, , | Summary: Gaussian Graphical models (GGM) are widely used to estimate the network structures in many applications ranging from biology to finance. In practice, data is often corrupted by latent confounders which biases inference of the underlying true graphical structure. […]

The Sizes of Quasar Host Galaxies with the Hyper Suprime-Cam Subaru Strategic Program

Kavli Affiliate: John D. Silverman | First 5 Authors: Junyao Li, John D. Silverman, Xuheng Ding, Michael A. Strauss, Andy Goulding | Summary: The relationship between quasars and their host galaxies provides clues on how supermassive black holes (SMBHs) and massive galaxies are jointly assembled. To elucidate this connection, we measure the structural and photometric […]

Sketching with Kerdock’s crayons: Fast sparsifying transforms for arbitrary linear maps

Kavli Affiliate: David Gross | First 5 Authors: Tim Fuchs, David Gross, Felix Krahmer, Richard Kueng, Dustin G. Mixon | Summary: Given an arbitrary matrix $Ainmathbb{R}^{ntimes n}$, we consider the fundamental problem of computing $Ax$ for any $xinmathbb{R}^n$ such that $Ax$ is $s$-sparse. While fast algorithms exist for particular choices of $A$, such as the […]

Thermal anyon interferometry in phonon-coupled Kitaev spin liquids

Kavli Affiliate: Joel E. Moore | First 5 Authors: Kai Klocke, Joel E. Moore, Jason Alicea, Gábor B. Halász, | Summary: Recent theoretical studies inspired by experiments on the Kitaev magnet $alpha$-RuCl$_3$ highlight the nontrivial impact of phonons on the thermal Hall conductivity of chiral topological phases. Here we introduce mixed mesoscopic-macroscopic devices that allow […]
