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 […]

The isotropic attractor solution of axion-SU(2) inflation: Universal isotropization in Bianchi type-I geometry

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Ira Wolfson, Azadeh Maleknejad, Tomoaki Murata, Eiichiro Komatsu, Tsutomu Kobayashi | Summary: SU(2) gauge fields coupled to an axion field can acquire an isotropic background solution during inflation. We study homogeneous but anisotropic inflationary solutions in the presence of such (massless) gauge fields. A gauge field in […]

AGN STORM 2: I. First results: A Change in the Weather of Mrk 817

Kavli Affiliate: Erin Kara | First 5 Authors: Erin Kara, Missagh Mehdipour, Gerard A. Kriss, Edward M. Cackett, Nahum Arav | Summary: We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for its historically unobscured nature, we […]

Adiabatic Construction of Hierarchical Quantum Hall States

Kavli Affiliate: Frank Wilczek | First 5 Authors: Martin Greiter, Frank Wilczek, , , | Summary: We propose an exact model of anyon ground states including higher Landau levels, and use it to obtain fractionally quantized Hall states at filling fractions $nu=p/(p(m-1)+1)$ with $m$ odd, from integer Hall states at $nu=p$ through adiabatic localization of […]

Design of a frequency-independent optic axis Pancharatnam-based achromatic half-wave plate

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Kunimoto Komatsu, Hirokazu Ishino, Nobuhiko Katayama, Tomotake Matsumura, Yuki Sakurai | Summary: Pancharatnam-based achromatic half-wave plates (AHWP) achieve high polarization efficiency over a broad waveband. These AWHPs generally contain a property whereby the optic axis is dependent on the electromagnetic frequency of the incident radiation. When the […]
