Unveiling the period-bounce population of cataclysmic variables: Spectroscopic and time-domain follow-up of eROSITA-selected candidates
S. Hernández-DÃaz, B. Stelzer, A. Schwope +9
The paper presents spectroscopic and time‑domain follow‑up of eROSITA‑selected cataclysmic variable candidates, confirming 24 new systems and showing they are consistent with perio…
The X-ray-Weak Tail of the Quasar Population: Physical Properties and Redshift Evolution of Variability-Selected AGN in eFEDS
P. Arévalo, J. Buchner, M. Salvato +10
The paper examines AGN identified through optical variability in the eROSITA eFEDS survey, comparing those detected in X‑rays to those that are not, and finds that a substantial hi…
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…
JWST Reveals Compact Nuclear Starbursts Masquerading as AGNs in Metal-Poor Dwarfs: Where Are the Accreting Intermediate-Mass Black Holes?
William Matzko, Shobita Satyapal, Jeffrey D. Mckaig +19
We present JWST/NIRSpec spectroscopy of the low-mass, metal-poor galaxy SDSS~J160135.95+311353.7 (J1601), selected for its extreme mid-infrared colors and compact nuclear emission,…
Direct Summation of the Madelung Constant Using Axial Multipoles
Joven V. Calara, Jan D. Miller
We present an absolutely convergent real-space summation method for electrostatic potentials in ionic lattices. The method constructs the lattice from translated axial multipole un…
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…
