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 […]
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. […]
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 […]
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 […]
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 […]
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 […]
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 […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Yilun Guan, Susan E. Clark, Brandon S. Hensley, Patricio A. Gallardo, Sigurd Naess | Summary: We present arcminute-resolution intensity and polarization maps of the Galactic center made with the Atacama Cosmology Telescope (ACT). The maps cover a 32 deg$^2$ field at 98, 150, and 224 GHz […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Jindian Liu, Liu Yan, Beichuan Zhang, Peng Luo | Summary: Name lookup is a key technology for the forwarding plane of content router in Named Data Networking (NDN). To realize the efficient name lookup, what counts is deploying a highperformance index in content routers. So […]
Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Mikhail A. Malkov, Igor V. Moskalenko, , , | Summary: Significant progress in cosmic ray (CR) studies was achieved over the past decade. Particularly important are precise measurements of primary and secondary species in the TV rigidity domain that show a bump in the spectra of […]
