Black Hole Feeding and Feedback in a Compact Galaxy

Kavli Affiliate: Feng Yuan | First 5 Authors: Yihuan Di, Yuan Li, Feng Yuan, Fangzheng Shi, Mirielle Caradonna | Summary: We perform high-resolution hydrodynamical simulations using the framework of {it MACER} to investigate supermassive black hole (SMBH) feeding and feedback in a massive compact galaxy, which has a small effective radius but a large stellar […]

Flux Calibration of CHIME/FRB Intensity Data

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Bridget C. Andersen, Chitrang Patel, Charanjot Brar, P. J. Boyle, Emmanuel Fonseca | Summary: Fast radio bursts (FRBs) are bright radio transients of micro-to-millisecond duration and unknown extragalactic origin. Central to the mystery of FRBs are their extremely high characteristic energies, which surpass the typical energies […]

Quasar Luminosity Function at z = 7

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa, Michael A. Strauss, Nobunari Kashikawa | Summary: We present the quasar luminosity function (LF) at $z = 7$, measured with 35 spectroscopically confirmed quasars at $6.55 < z < 7.15$. The sample of 22 quasars from the Subaru High-$z$ Exploration of […]

The precursor of GRB211211A: a tide-induced giant quake?

Kavli Affiliate: Lijing Shao | First 5 Authors: Enping Zhou, Yong Gao, Yurui Zhou, Xiaoyu Lai, Lijing Shao | Summary: The equilibrium configuration of a solid strange star in the final inspiral phase with another compact object is generally discussed, and the starquake-related issue is revisited, for a special purpose to understand the precursor emission […]

The First X-ray Polarization Observation of the Black Hole X-ray Binary 4U 1630-47 in the Steep Power Law State

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Nicole Rodriguez Cavero, Lorenzo Marra, Henric Krawczynski, Michal Dovčiak, Stefano Bianchi | Summary: The Imaging X-ray Polarimetry Explorer (IXPE) observed the black hole X-ray binary 4U 1630-47 in the steep power law (or very high) state. The observations reveal a linear polarization degree of the 2-8 […]

Detecting Exoplanets Closer to Stars with Moderate Spectral Resolution Integral-Field Spectroscopy

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Shubh Agrawal, Jean-Baptiste Ruffio, Quinn M. Konopacky, Bruce Macintosh, Dimitri Mawet | Summary: While radial velocity surveys have demonstrated that the population of gas giants peaks around $3~text{au}$, the most recent high-contrast imaging surveys have only been sensitive to planets beyond $sim~10~text{au}$. Sensitivity at small angular separations […]

Duality Origami: Emergent Ensemble Symmetries in Holography and Swampland

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jacob M. Leedom, Masahito Yamazaki | Summary: We discuss interrelations between several ideas in quantum gravity. One is the Swampland program, which states that a low-energy effective field theory should satisfy non-trivial constraints to have an ultraviolet (UV) completion in quantum gravity. Another is the […]

Gravitational Positivity for Phenomenologists: Dark Gauge Boson in the Swampland

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Katsuki Aoki, Toshifumi Noumi, Ryo Saito, Sota Sato, Satoshi Shirai | Summary: The gravitational positivity bound gives quantitative “swampland” constraints on low-energy effective theories inside theories of quantum gravity. We give a comprehensive discussion of this bound for those interested in applications to phenomenological model building. We […]

Measuring $μ$-Distortions from the Thermal Sunyaev-Zeldovich effect

Kavli Affiliate: Wayne Hu | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: The thermal Sunyaev-Zel’dovich (tSZ) effect is a spectral distortion of the cosmic microwave background (CMB) resulting from inverse Compton scattering of CMB photons with electrons in the medium of galaxy clusters. The spectrum of the tSZ effect is typically calculated […]

A non-linear solution to the $S_8$ tension II: Analysis of DES Year 3 cosmic shear

Kavli Affiliate: George Efstathiou | First 5 Authors: Calvin Preston, Alexandra Amon, George Efstathiou | Summary: Weak galaxy lensing surveys have consistently reported low values of the $S_8$ parameter compared to the $textit{Planck} Lambdarm{CDM}$ cosmology. Amon & Efstathiou (2022) used KiDS-1000 cosmic shear measurements to propose that this tension can be reconciled if the matter […]
