GA-NIFS: the interplay between merger, star formation and chemical enrichment in MACS1149-JD1 at z=9.11 with JWST/NIRSpec

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Cosimo Marconcini, Francesco D’Eugenio, Roberto Maiolino, Santiago Arribas, Andrew J. Bunker | Summary: We present JWST/NIRSpec integral-field spectroscopy observations of the z ~ 9.11 lensed galaxy MACS1149-JD1, as part of the GA-NIFS programme. The data was obtained with both the G395H grating (R~ 2700) and the prism […]

Modeling X-Ray Multi-Reflection in Super-Eddington Winds

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Zijian Zhang, Lars Lund Thomsen, Lixin Dai, Christopher S. Reynolds, Javier A. García | Summary: It has been recently discovered that a few super-Eddington sources undergoing black hole super-Eddington accretion exhibit X-ray reflection signatures. In such new systems, one expects that the coronal X-ray emissions are mainly […]

The white-light superflares from cool stars in GWAC triggers

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Guang-Wei Li, Liang Wang, Hai-Long Yuan, Li-Ping Xin, Jing Wang | Summary: M-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-type stars that triggered the […]

On the interplay of electronic and lattice screening on exciton binding in two-dimensional lead halide perovskites

Posted by dbos Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Rohit Rana, David T. Limmer, , , | Summary: We use path integral Monte Carlo to study the energetics of excitons in layered, hybrid organic-inorganic perovskites in order to elucidate the relative contributions of dielectric confinement and electron-phonon coupling. While the dielectric mismatch between polar perovskite […]
