Simulating Continuum-based Redshift Measurement in the Roman’s High Latitude Spectroscopic Survey

The Astronomical Journal
We investigate the capability of the Nancy Grace Roman Space Telescope’s (Roman) Wide-Field Instrument G150 slitless grism to detect red, quiescent galaxies based on the current reference survey.

A test for the redshift dependence of $$\sigma _8$$ σ 8 using $$f\sigma _8$$ f σ 8 measurements

European Physical Journal C: Particles and Fields
We search for a redshift dependence of $$\sigma _8^0$$ σ 8 0 using 23 growth rate measurements from redshift space distortions and peculiar velocity measurements as a consistency check of $$\Lambda $$ Λ CDM.

Study on the Gamma-Ray Radiation Properties of High-Redshift Blazars at z > 2.5

Universe
The high-redshift blazars are important cosmological probes for exploring the early universe and unraveling the fundamental emission processes and the structure of the active galactic nuclei.

The spatial distribution of GRBs

Acta Polytechnica
We analysed the different aspects of the spatial distribution of 542 Gamma-Ray Bursts with precisely determined positions and spectroscopic redshifts. The data were divided according to the origin of the redshift (afterglow or host galaxy).

The High-Redshift Gas-Phase Mass–Metallicity Relation in FIRE-2

The Astrophysical Journal Letters
The unprecedented infrared spectroscopic capabilities of JWST have provided high-quality interstellar medium metallicity measurements and enabled characterization of the gas-phase mass–metallicity relation (MZR) for galaxies at z ≳ 5 for the first time ...
