In this article, the atomic neutral hydrogen (H I) content of ∼1600 galaxies up to z ∼ 0.1 was studied using stacking techniques. But the results were limited to the SDSS South Galactic Cap.
Abstract
We study the atomic neutral hydrogen (H I) content of ∼1600 galaxies up to z ∼ 0.1 using stacking techniques. The observations were carried out with the Westerbork Synthesis Radio Telescope (WSRT) in the area of the SDSS South Galactic Cap (SSGC), where we selected a galaxy sample from the SDSS spectroscopic catalog. Multi-wavelength information is provided by SDSS, NVSS, GALEX, and WISE. We use the collected information to study H I trends with color, star-forming, and active galactic nuclei (AGN) properties. Using near-UV (NUV) − r colors, galaxies are divided into blue cloud, green valley and red sequence galaxies. As expected based on previous observations, we detect H I in green valley objects with lower amounts of H I than blue galaxies, while stacking only

Cold gas stripping in satellite galaxies: from pairs to clusters

TL;DR: In this paper, the authors investigate environment driven gas depletion in satellite galaxies, taking full advantage of the atomic hydrogen (HI) spectral stacking technique to quantify the gas content for the entire gas-poor to -rich regime.

The Many Routes to AGN Feedback

TL;DR: In this article, a review summarizes some of the recent observational results obtained in different wavebands, tracing different phases of the gas, and summarizes the new insights they have brought, and the constraints they provide to numerical simulations of galaxy formation and evolution.

AGN feedback and star formation of quasar host galaxies: insights from the molecular gas

TL;DR: In this paper, the authors used CO(2-1) observations from a new ALMA survey, in conjunction with literature measurements, to investigate the molecular gas properties of a representative sample of 40 z < 0.3 Palomar-Green quasars.

Extragalactic HI surveys

TL;DR: In this paper, the authors review the results of HI line surveys of extragalactic sources in the local universe and provide an overview of currently ongoing and planned surveys which will explore the cosmic evolution of properties of the HI population.

The Sloan Digital Sky Survey: Technical Summary

Donald G. York
- 27 Jun 2000 - 
TL;DR: The Sloan Digital Sky Survey (SDSS) as mentioned in this paper provides the data to support detailed investigations of the distribution of luminous and non-luminous matter in the Universe: a photometrically and astrometrically calibrated digital imaging survey of pi steradians above about Galactic latitude 30 degrees in five broad optical bands.

The Global Schmidt law in star forming galaxies

TL;DR: In this paper, the Schmidt law was used to model the global star formation law over the full range of gas densities and star formation rates observed in galaxies, and the results showed that the SFR scales with the ratio of the gas density to the average orbital timescale.
