A Pilot Study for the CSST Slitless Spectroscopic Quasar Survey Based on Mock Data

open access: yesThe Astrophysical Journal
The wide survey of the Chinese Space Station Telescope (CSST) will observe a large field of 17,500 deg ^2 . The GU, GV, and GI grism observations of CSST will cover the wavelength range from 2550 to 10000 Å at a resolution of R  ∼ 200 and a depth of ...

Cross Calibration of Galaxy Cluster Temperatures Measured with NuSTAR, XMM-Newton, and Chandra

open access: yesThe Astrophysical Journal
The use of galaxy clusters to constrain cosmology is limited in part due to uncertainties in derived cluster masses, which often depend on the gas temperature. Unfortunately, there exists a longstanding discrepancy in temperature measurements of the same

Spatial Distribution of Intracluster Light versus Dark Matter in Horizon Run 5

open access: yesThe Astrophysical Journal
One intriguing approach for studying the dynamical evolution of galaxy clusters is to compare the spatial distributions among various components such as dark matter, member galaxies, gas, and intracluster light (ICL).

Discovery of Weak O VI Absorption in Underdense Regions of the Low-redshift Intergalactic Medium

open access: yesThe Astrophysical Journal
We search for weak O vi absorption in the low-redshift intergalactic medium (IGM) using 82 high signal-to-noise quasar spectra from the Cosmic Origins Spectrograph on the Hubble Space Telescope.

Evidence for a Shallow Evolution in the Volume Densities of Massive Galaxies at z = 4–8 from CEERS

open access: yesThe Astronomical Journal
We analyze the evolution of massive (log _10 [ M _⋆ / M _⊙ ] > 10) galaxies at z ∼ 1–4 selected from JWST Cosmic Evolution Early Release Survey (CEERS). We infer the physical properties of all galaxies in the CEERS NIRCam imaging through spectral energy ...
