Variability in gamma-ray sources
, 2019 Gamma-rays are known to be emitted from some of the most extreme sources in the known Universe. Many of these objects are volatile and variable, and understanding them is the focus of the work contained in this thesis. One such class of objects which are highly variable in gamma-rays are blazars, which are known to be variable on $\sim$ minute ...

Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses
Advanced Materials, EarlyView.Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...

A Leptonic Interpretation of the Ultra-high-energy Gamma-Ray Emission from V4641 Sgr
The Astrophysical JournalRecently, the microquasar V4641 Sgr and its surrounding have been detected at TeV–PeV gamma-ray band. Interestingly, the spectrum follows a power-law function continuing up to 0.8 PeV as reported by LHAASO, and the morphology of the emission appears to ...

Advanced Materials, EarlyView.Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Ultra-high-energy Cosmic-Ray Sources Can Be Gamma-Ray Dim
The Astrophysical Journal LettersUltra-high-energy cosmic rays (UHECRs), accelerated hadrons that can exceed energies of 10 ^20 eV, are the highest-energy particles ever observed. While the sources producing UHECRs are still unknown, the Pierre Auger Observatory has detected a large ...
