Galaxy Clusters from the DESI Legacy Imaging Surveys.II. Environment effects on size-mass relation

Zhaobin Chen, Yizhou Gu, Hu Zou +1

To investigate the environment effects on size growth of galaxies, we study the size-mass relation across a broad range of environment with a vast sample of approximately 32 millio…

The Accretion History of the Milky Way: III. Hydrodynamical Simulations of Galactic Dwarf Galaxies at First Infall

Jianling Wang, Francois Hammer, Yanbin Yang +3

Most Milky Way dwarf galaxies are much less bound to their host than are relics of Gaia-Sausage-Enceladus and Sgr. These dwarfs are expected to have fallen into the Galactic halo l…

The accretion history of the Milky Way. II. Internal kinematics of globular clusters and of dwarf galaxies

Francois Hammer, Jianling Wang, Gary A. Mamon +7

We study how structural properties of globular clusters and dwarf galaxies are linked to their orbits in the Milky Way halo. From the inner to the outer halo, orbital energy increa…

Spatial distribution of NH2D in massive star-forming regions

Yuqiang Li, Junzhi Wang, Juan Li +4

To understand the relation between NHD and its physical environment, we mapped ortho-NHD at 85.9 GHz toward 24 Galactic late-stage massive star-forming…

DESI Legacy Imaging Surveys Data Release 9: Cosmological Constraints from Galaxy Clustering and Weak Lensing using the Minimal Bias Model

Haojie Xu, Hekun Li, Jun Zhang +11

We present a tentative constraint on cosmological parameters and from a joint analysis of galaxy clustering and galaxy-galaxy lensing from DESI Legacy Imaging Surveys D…

First M87 Event Horizon Telescope Results. IX. Detection of Near-horizon Circular Polarization

The Event Horizon Telescope Collaboration

Event Horizon Telescope (EHT) observations have revealed a bright ring of emission around the supermassive black hole at the center of the M87 galaxy. EHT images in linear polariza…
