DESI Spectroscopy of HETDEX Emission-line Candidates. I. Line Discrimination Validation
The Astrophysical JournalThe Hobby–Eberly Dark Energy Experiment (HETDEX) is an untargeted spectroscopic galaxy survey that uses Ly α- emitting galaxies (LAEs) as tracers of 1.9 < z < 3.5 large-scale structure. Most detections consist of a single emission line, whose identity is Martin Landriau, Erin Mentuch Cooper, Dustin Davis, Karl Gebhardt, Robin Ciardullo, Éric Armengaud, Arjun Dey, Anand Raichoor, David J.

The Astrophysical Journal, 2001 The least-action principle (LAP) method is used on four galaxy redshift surveys to measure the density parameter Omega_m and the matter and galaxy-galaxy power spectra. The datasets are PSCz, ORS, Mark III and SFI. The LAP method is applied on the surveys simultaneously, resulting in an overconstrained dynamical system that describes the cosmic ...openaire +2 more sourcesEuclid: Quick Data Release (Q1) – Watching ICM-selected galaxy clusters with Euclid eyes: Prospects of Euclid data in the context of large SZE- and X-ray-based surveys★
Astronomy & AstrophysicsGalaxy clusters detected through their X-ray emission or Sunyaev–Zeldovich effect (SZE), both produced by the intracluster medium (ICM), have been successfully used in cosmological and astrophysical studies.Klein M., George K., Mohr J.

The Astrophysical JournalWe investigate the expected accuracy of redshifts that can be obtained using low-resolution spectroscopic (medium-band) data from the 7-Dimensional Sky Survey (7DS). By leveraging 40 densely sampled filters with widths of FWHM = 25 nm, we create 7DS mock Eunhee Ko, Myungshin Im, Yujin Yang, Ji Hoon Kim, Seong-Kook Lee, Gregory S.-H.
