Probing inflationary gravitational waves with cross-correlations: improved forecasting and validation with simulations

Posted by dbos Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Irene Abril-Cabezas, Blake D. Sherwin, , | Summary: We present a follow-up study to the method recently proposed by Namikawa & Sherwin (2023) to probe gravitational waves using cross-correlations between two CMB $B$-modes and a large-scale structure tracer. We first improve on the previous forecast […]

On the Extremely X-ray Variable Active Galactic Nuclei in the XMM-LSS Field

Posted by dbos Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Zijian Zhang, Bin Luo, Linhua Jiang, W. N. Brandt, Jian Huang | Summary: We present a systematic investigation of extremely X-ray variable active galactic nuclei (AGNs) in the $approx 5.3~{rm deg}^2$ XMM-SERVS XMM-LSS region. Eight variable AGNs are identified with rest-frame 2 keV flux density variability amplitudes […]

Duality viewpoint of noninvertible symmetry protected topological phases

Posted by dbos Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Masahito Yamazaki, Linhao Li, , | Summary: Recent advancements in generalized symmetries have drawn significant attention to gapped phases of matter exhibiting novel symmetries, such as noninvertible symmetries. By leveraging the duality transformations, the classification and construction of gapped phases with noninvertible symmetry can be […]

Temperature Profiles of Accretion Disks in Luminous Active Galactic Nuclei derived from Ultraviolet Spectroscopic Variability

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Suyeon Son, Minjin Kim, Luis C. Ho, , | Summary: The characteristic timescale ($tau$) of continuum variability of the accretion disk in active galactic nuclei (AGNs) is known to be related to the thermal timescale, which is predicted to scale with AGN luminosity ($L$) and restframe […]
