Using Host Galaxy Photometric Redshifts to Improve Cosmological Constraints with Type Ia Supernova in the LSST Era

Kavli Affiliate: Richard Kessler | First 5 Authors: Ayan Mitra, Richard Kessler, Surhud More, Renee Hlozek, The LSST Dark Energy Science Collaboration | Summary: We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using only the "zspec" subset with spectroscopic redshifts […]

Probable low-frequency quasi-periodic oscillations in blazars from the ZTF survey

Kavli Affiliate: Luis C. Ho | First 5 Authors: Anuvab Banerjee, Vibhore Negi, Ravi Joshi, Nagendra Kumar, Paul J. Wiita | Summary: We investigate the possible presence of quasi-periodic oscillation (QPO) signals in 2103 blazars from the Zwicky Transient Facility (ZTF) time-domain survey. We detect a low-frequency QPO signal in five blazars observed over these […]

A Transient `Changing-Look’ AGN Resolved on Month Timescales From First-Year SDSS-V Data

Kavli Affiliate: Claudio Ricci | First 5 Authors: Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous, Jessie Runnoe, Jonathan R. Trump | Summary: We report the discovery of a new `changing-look’ active galactic nucleus (CLAGN) event, in the quasar SDSS J162829.17+432948.5 at z=0.2603, identified through repeat spectroscopy from the fifth Sloan Digital Sky Survey (SDSS-V). Optical photometry […]

Toroidal flux loss due to flux emergence explains why solar cycles rise differently but decay in a similar way

Kavli Affiliate: Robert Cameron | First 5 Authors: Akash Biswas, Bidya Binay Karak, Robert Cameron, , | Summary: A striking feature of the solar cycle is that at the beginning, sunspots appear around mid-latitudes, and over time the latitudes of emergences migrate towards the equator.The maximum level of activity (e.g., sunspot number) varies from cycle […]

Super-horizon resonant magnetogenesis during inflation

Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Valeri Vardanyan, Vicharit Yingcharoenrat, , | Summary: We propose a novel mechanism for significantly enhancing the amplitude of primordial electromagnetic fields during inflation. Similar to existing proposals, our idea is based on parametric resonance effects due to conformal-symmetry-breaking coupling of the gauge field and the […]

Superconductivity in doped triangular Mott insulators: the roles of parent spin backgrounds and charge kinetic energy

Kavli Affiliate: Zheng Zhu | First 5 Authors: Zheng Zhu, Qianqian Chen, , , | Summary: We study the prerequisites for realizing superconductivity in doped triangular-lattice Mott insulators by considering three distinct parent spin backgrounds, i.e., $120^{circ}$ antiferromagnets, quantum spin liquid, and stripy antiferromagnets, and all possible sign combinations $(tau_1, tau_2)$ of nearest-neighbor hopping and […]
