Photometric Redshifts and High‐Redshift Galaxies [PDF]
The Workshop "Photometric Redshifts and High‐Redshift Galaxies" was held at the Observatories of the Carnegie Institution of Washington, in Pasadena, California, on 1999 April 28–30. The 70 participants were greeted with atypically cool, overcast weather, but this did not cloud or dampen the discussions.

Evolution of Interstellar Medium, Star Formation, and Accretion at High Redshift [PDF]
ALMA observations of the long wavelength dust continuum are used to estimate the interstellar medium (ISM) masses in a sample of 708 galaxies at z = 0.3 to 4.5 in the COSMOS field.

On the dust temperatures of high-redshift galaxies [PDF]
Dust temperature is an important property of the interstellar medium (ISM) of galaxies. It is required when converting (sub)millimetre broad-band flux to total infrared luminosity (LIR), and hence star formation rate, in high-redshift galaxies. However,

Fast Radio Burst Energy Function in the Presence of DMhost Variation
Fast radio bursts (FRBs) have been found in great numbers, but the physical mechanism of these sources is still a mystery. The redshift evolutions of the FRB energy distribution function and the volumetric rate shed light on the origin of FRBs.

The Origin of Low-redshift Event Rate Excess as Revealed by the Low-luminosity Gamma-Ray Bursts
The relation between the event rate of long gamma-ray bursts and the star formation rate is still controversial, especially at the low-redshift end. Dong et al.

Gravitational Redshift Test Using Eccentric Galileo Satellites. [PDF]
We report on a new test of the gravitational redshift and thus of local position invariance, an integral part of the Einstein equivalence principle, which is the foundation of general relativity and all metric theories of gravitation.

The Redshift of the BL Lac Object TXS 0506+056 [PDF]
The bright BL Lac object TXS 0506+056 is the most likely counterpart of the IceCube neutrino event EHE 170922A. The lack of this redshift prevents a comprehensive understanding of the modeling of the source.

The Complete Calibration of the Color–Redshift Relation (C3R2) Survey: Analysis and Data Release 2 [PDF]
The Complete Calibration of the Color-Redshift Relation (C3R2) survey is a multi-institution, multi-instrument survey that aims to map the empirical relation of galaxy color to redshift to i ∼ 24.5 (AB), thereby providing a firm foundation for weak ...

Leveraging Machine Learning for Photometric Redshift Estimation of JWST Galaxies
With the launch of JWST, the volume and complexity of astronomical data are increasing, a trend that will continue with future instruments such as SKA and Euclid. It is inevitable that data-driven methods will become more prominent alongside model-driven
