Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Luis Enrique Pérez-Montaño, Vicente Rodriguez-Gomez, Bernardo Cervantes Sodi, Qirong Zhu, Annalisa Pillepich | Summary: We explore the nature of low surface brightness galaxies (LSBGs) in the hydrodynamic cosmological simulation TNG100 of the IllustrisTNG project, selecting a sample of LSBGs ($r$-band effective surface brightness $mu_r > 22.0$ mag […]
Kavli Affiliate: Ke Wang | First 5 Authors: Jian-Wen Zhou, Tie Liu, Neal J. Evans II, Guido Garay, Paul F. Goldsmith | Summary: We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using H$^{13}$CO$^{+}$ J=1-0 molecular line data obtained from the ATOMS survey. We find that filaments are ubiquitous […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Anirudh Chiti, Yohai Meiron, Kaley V. Brauer | Summary: We have developed a chemo-dynamical approach to assign 36,010 metal-poor SkyMapper stars to various Galactic stellar populations. Using two independent techniques (velocity and action space behavior), $Gaia$ EDR3 astrometry, and photometric metallicities, we […]
Kavli Affiliate: Jing Wang | First 5 Authors: Hong Guo, Michael G. Jones, Jing Wang, , | Summary: The growth of supermassive black holes, especially the associated state of active galactic nuclei (AGNs), is generally believed to be the key step in regulating star formation in massive galaxies. As the fuel of star formation, the […]

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We report the measurement of the branching fraction of the $B^0 to K_S^0 pi^0 gamma$ decay in $e^+ e^- to Upsilon(4S) to B overline{B}$ data recorded by the Belle II experiment at the SuperKEKB […]
Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Zhongfu Zhang, , , | Summary: Extreme-mass-ratio inspirals (EMRIs) are important sources for space-borne gravitational-wave (GW) detectors. Such a source normally consists of a stellar-mass black hole (BH) and a Kerr supermassive BH (SMBH), but recent astrophysical models predict that the small body could also […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We present a reconstruction of the semileptonic decays $B^0 to pi^- e^+ nu_e$ and $B^+ to pi^0 e^+ nu_e$ in a sample corresponding to 189.3 fb$^{-1}$ of Belle II data, using events where the […]

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: For conformally invariant gravity theories defined on Riemannian spacetime and having the Schwarzschild–de-Sitter (SdS) metric as a solution in the Einstein gauge, we consider whether one may conformally rescale this solution to obtain flat rotation curves, such as those […]
