Kavli Affiliate: Lars Bildsten | First 5 Authors: Viraj R. Karambelkar, Mansi M. Kasliwal, Patrick Tisserand, Shreya Anand, Michael C. B. Ashley | Summary: We present results from a systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, using data from the Palomar Gattini IR (PGIR) survey. R Coronae Borealis […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ignas Juodžbalis, Xihan Ji, Roberto Maiolino, Francesco D’Eugenio, Jan Scholtz | Summary: JWST has discovered a large population of Active Galactic Nuclei (AGN) at high redshift. Many of these newly discovered AGN have broad permitted lines (typically H$alpha$), but are extremely weak in the X-rays. Here we […]

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 […]
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 […]

Kavli Affiliate: Simon Groblacher | First 5 Authors: Bruno Lopez-Rodriguez, Naresh Sharma, Zizheng Li, Roald van der Kolk, Jasper van der Boom | Summary: Integrated photonic circuits have transformed data communication, biosensing, and light detection and ranging, and hold wide-ranging potential for optical computing, optical imaging and signal processing. These applications often require tunable and […]
Kavli Affiliate: David Spergel | First 5 Authors: Masato Shirasaki, Cristóbal Sifón, Hironao Miyatake, Erwin Lau, Zhuowen Zhang | Summary: We present a stacked lensing analysis of 96 galaxy clusters selected by the thermal Sunyaev-Zel’dovich (SZ) effect in maps of the cosmic microwave background (CMB). We select foreground galaxy clusters with a $5sigma$-level SZ threshold […]

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 […]
