Kavli Affiliate: John D. Silverman | First 5 Authors: Jia-Lai Kang, Chris Done, Scott Hagen, Matthew J. Temple, John D. Silverman | Summary: A recent study on the spectral energy distribution (SED) of AGN combined unobscured X-ray sources from the eROSITA eFEDS Survey with high quality optical imaging from Subaru’s Hyper Suprime-Cam (HSC). The HSC […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Jie Liao, Ning Chang, Lang Cui, Pengfei Jiang, Didong Mou | Summary: Type-C quasi-periodic oscillations (QPOs) in black hole X-ray transients typically manifest in the low-hard and hard-intermediate states. This study presents a detailed spectral and temporal analysis of the black hole candidate Swift J1727.8-1613 using […]

Kavli Affiliate: Peter W. Graham | First 5 Authors: Xing Fan, Gerald Gabrielse, Peter W. Graham, Harikrishnan Ramani, Samuel S. Y. Wong | Summary: We propose using highly excited cyclotron states of a trapped electron to detect meV axion and dark photon dark matter, marking a significant improvement over our previous proposal and demonstration [Phys. […]
Kavli Affiliate: Ruobing Dong | First 5 Authors: Kan Chen, Ruobing Dong, , , | Summary: Planet-disk interactions can produce kinematic signatures in protoplanetary disks. While recent observations have detected non-Keplerian gas motions in disks, their origins are still being debated. To explore this, we conduct 3D hydrodynamic simulations using the code FARGO3D to study […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Ellen M. Price, Juliette Becker, Zoë L. de Beurs, Leslie A. Rogers, Andrew Vanderburg | Summary: HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital period and deep transit make it an ideal candidate for detecting oblateness photometrically. We present a […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Crispin Turner, Sandro Tacchella, Francesco D’Eugenio, Stefano Carniani, Mirko Curti | Summary: We present a detailed analysis of JWST/NIRSpec and NIRCam observations of ZF-UDS-7329, a massive, quiescent galaxy at redshift $z=3.2$, which has been put forward to challenge cosmology and galaxy formation physics. Our study extends previous […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, , , , | Summary: We for the first time constrain anisotropic cosmic birefringence generated at reionization using Planck PR4 polarization data. Several recent analyses of WMAP and Planck polarization data have found a tantalizing hint of isotropic cosmic birefringence. Ongoing and future CMB experiments […]
