A broadband outburst of the compact steep-spectrum quasar 3C 138 in 2024-2026
T. V. Mufakharov, Yu. V. Sotnikova, V. V. Vlasyuk +20
After several decades of relative quiescence, the compact steep-spectrum quasar 3C 138 entered an active phase in 2024-2026, exhibiting strong broadband flaring. We investigate its…
Evaluation of PID Performance at CEPC and Optimization with Combined dN/dx and Time-of-Flight Data
Dian Yu, Houqian Ding, Yongfeng Zhu +3
Charged-hadron identification (PID) is a critical requirement for the physics program of the Circular Electron-Positron Collider (CEPC). The baseline detector relies on ionization…
Orbital chiral lasing in twisted bilayer metasurfaces
Mingjin Wang, Nianyuan Lv, Zixuan Zhang +11
Chirality is a fundamental concept in physics that underpins various phenomena in nonlinear optics, quantum physics, and topological photonics. Although the spin of a photon natura…
On unveiling Buried Nuclei with JWST: a technique for hunting the most obscured galaxy nuclei from local to high redshift
I. GarcÃa-Bernete, F. R. Donnan, D. Rigopoulou +12
We analyze JWST NIRSpec+MIRI/MRS observations of the infrared (IR) Polycyclic Aromatic Hydrocarbon (PAH) features in the central regions (0.26'' at 6 micron; 50-440 pc…
CO-CHANGES II: spatially resolved IRAM 30M CO line observations of 23 nearby edge-on spiral galaxies
Yan Jiang, Jiang-Tao Li, Qing-Hua Tan +6
Molecular gas, as the fuel for star formation, and its relationship with atomic gas are crucial for understanding how galaxies regulate their star forming (SF) activities. We condu…
