Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We report measurements of time-dependent $CP$ asymmetries in $B^0 to K^0_S pi^0 gamma$ decays based on a data sample of $(388pm6)times10^6$ $Bbar{B}$ events collected at the $Upsilon(4S)$ resonance with the Belle II detector. The […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, L. Aggarwal, H. Aihara | Summary: We present measurements of $B^{+}rightarrowrho^{+}gamma$ and $B^{0}rightarrowrho^{0}gamma$ decays using a combined data sample of $772 times 10^6$ $Boverline{B}$ pairs collected by the Belle experiment and $387times 10^6$ $Boverline{B}$ pairs collected by the Belle II […]

Kavli Affiliate: Eric Oberla | First 5 Authors: Jinseo Park, Evan Angelico, Andrew Arzac, Davide Braga, Ahan Datta | Summary: 1 ps timing resolution is the entry point to signature based searches relying on secondary/tertiary vertices and particle identification. We describe a preliminary design for PSEC5, an 8-channel 40 GS/s waveform-sampling ASIC in the TSMC […]

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: 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 […]
