Physically motivated AGN emissivity profiles and their effects on quasar microlensing signatures. 1. Multi-epoch accretion disc size inference

Scott Hagen, Carina Fian

Quasar microlensing is uniquely sensitive to the size-scale of the accretion flow, offering one of the few direct probes of the accretion structure on micro-arcsecond scales. Howev…

The performance of the TA4 surface detector array: 4.3 years of the first-half expansion

Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +128

The Telescope Array (TA) experiment aims to reveal the origin of ultra-high-energy cosmic rays (UHECRs) by observing air showers using surface detectors (SDs), which spread over an…

Euclid preparation. Decomposing components of the extragalactic background light using multi-band intensity mapping cross-correlations

Euclid Collaboration, Y. Cao, A. R. Cooray +269

The extragalactic background light (EBL) fluctuations in the optical/near-IR encode the cumulative integrated galaxy light (IGL), diffuse intra-halo light (IHL), and high- sourc…

Searching for EeV photons with Telescope Array Surface Detector and neural networks

Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126

Ultra-high-energy photons play an important role in probing astrophysical models and beyond-Standard-Model scenarios. We report updated limits on the diffuse photon flux using Tele…

Cosmic ray mass composition measurement in the energy range from eV to eV observed with the TALE hybrid detector

Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126

We report on the cosmic ray mass composition measured by the Telescope Array Low-energy Extension (TALE) hybrid detector. The TALE detector consists of a fluorescence detector (FD)…

Euclid preparation. Review of forecast constraints on dark energy and modified gravity

Euclid Collaboration, N. Frusciante, M. Martinelli +326

The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…
