A DECADE of dwarfs: first detection of weak lensing around spectroscopically confirmed low-mass galaxies

Posted by klaurent Chicago

Kavli Affiliate: Chihway Chang | First 5 Authors: Chun-Hao To, Chun-Hao To, , , | Summary: We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECADE/DES weak lensing catalogs. A clean dwarf galaxy sample with well-defined redshift and stellar mass […]

Neural Networks as Surrogate Solvers for Time-Dependent Accretion Disk Dynamics

Posted by klaurent Peking

Kavli Affiliate: Lile Wang | First 5 Authors: Shunyuan Mao, Shunyuan Mao, , , | Summary: Accretion disks are ubiquitous in astrophysics, appearing in diverse environments from planet-forming systems to X-ray binaries and active galactic nuclei. Traditionally, modeling their dynamics requires computationally intensive (magneto)hydrodynamic simulations. Recently, Physics-Informed Neural Networks (PINNs) have emerged as a promising […]
