The redshift distribution of dusty star forming galaxies from the SPT survey [PDF]

, 2016
We use the Atacama Large Millimeter/submillimeter Array (ALMA) in Cycle 1 to determine spectroscopic redshifts of high-redshift dusty star-forming galaxies (DSFGs) selected by their 1.4mm continuum emission in the South Pole Telescope (SPT) survey.

Redshift Survey of 12 Moderate-redshift Clusters

Research Notes of the AAS, 2022
Abstract We conducted a redshift survey of 12 X-ray selected clusters in the redshift range z = 0.35–0.50 with MMT/Hectospec. The redshift surveys confirm that these clusters are massive systems. There are no massive groups or clusters projected along the line of sight that might contaminate the observed cluster X-ray properties ...

The 2dF Galaxy Redshift Survey: power-spectrum analysis of the final data set and cosmological implications [PDF]

, 2005
We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS), employing a direct Fourier method. The sample used comprises 221 414 galaxies with measured redshifts.

Does the Black Hole Merger Rate Evolve with Redshift? [PDF]

Astrophysical Journal, 2018
We explore the ability of gravitational-wave detectors to extract the redshift distribution of binary black hole (BBH) mergers. The evolution of the merger rate across redshifts 0 < z ≲ 1 is directly tied to the formation and evolutionary processes ...

Variable G versus the Accelerated Expansion of the Universe

Open Astronomy, 2017
It is shown that the hypothesis of permitting variability of the Newtonian constant G, increasing with the local density of dark matter, implies that there is no need for the introduction of a cosmological constant or accelerated expansion of the ...

On estimating redshift and luminosity distributions in photometric redshift surveys [PDF]

, 2007
The luminosity functions of galaxies and quasars provide invaluable information about galaxy and quasar formation. Estimating the luminosity function from magnitude limited samples is relatively straightforward, provided that the distances to the objects

The Zwicky Transient Facility Bright Transient Survey. I. Spectroscopic Classification and the Redshift Completeness of Local Galaxy Catalogs [PDF]

Astrophysical Journal, 2019
The Zwicky Transient Facility (ZTF) is performing a three-day cadence survey of the visible northern sky (∼3π) with newly found transient candidates announced via public alerts.

Hydrogen Intramolecular Stretch Redshift in the Electrostatic Environment of Type II Clathrate Hydrates from Schrödinger Equation Treatment

Applied Sciences, 2020
The one-dimensional Schrödinger equation, applied to the H2 intramolecular stretch coordinate in singly to quadruply occupied large cages in extended Type II (sII) hydrogen clathrate hydrate, was solved numerically herein via potential-energy scans from ...

Measurement of redshift dependent cross correlation of HSC clusters and Fermi $\gamma$ rays [PDF]

, 2019
The cross-correlation study of the unresolved $\gamma$-ray background (UGRB) with galaxy clusters has a potential to reveal the nature of the UGRB. In this paper, we perform a cross-correlation analysis between $\gamma$-ray data by the Fermi Large Area ...

The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey DR14 quasar sample: a tomographic measurement of cosmic structure growth and expansion rate based on optimal redshift weights [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We develop a new method, which is based on the optimal redshift weighting scheme, to extract the maximal tomographic information of baryonic acoustic oscillations (BAO) and redshift space distortions (RSD) from the extended Baryon Oscillation ...
