Determination of the Cosmic Distance Scale from Sunyaev-Zel’dovich Effect and Chandra X-Ray Measurements of High-Redshift Galaxy Clusters [PDF]

, 2005
We determine the distance to 38 clusters of galaxies in the redshift range 0.14 ≤ z ≤ 0.89 using X-ray data from Chandra and Sunyaev-Zeldovich effect (SZE) data from the Owens Valley Radio Observatory and the Berkeley-Illinois-Maryland Association ...

Scaling Relations from Sunyaev-Zel’dovich Effect and Chandra X-Ray Measurements of High-Redshift Galaxy Clusters [PDF]

, 2007
We present Sunyaev-Zel’dovich Effect (SZE) scaling relations for 38 massive galaxy clusters at redshifts 0.14 ⩽ z⩽ 0.89, observed with both the Chandra X-ray Observatory and the centimeter-wave SZE imaging system at the BIMA and OVRO interferometric ...

ODIN: Where Do Lyα Blobs Live? Contextualizing Blob Environments within Large-scale Structure

The Astrophysical Journal, 2023
While many Ly α blobs (LABs) are found in and around several well-known protoclusters at high redshift, how they trace the underlying large-scale structure is still poorly understood. In this work, we utilize 5352 Ly α emitters (LAEs) and 129 LABs at z =

RELICS: The Reionization Lensing Cluster Survey and the Brightest High-z Galaxies [PDF]

, 2020
Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a view into both the extremely distant and intrinsically faint galaxy populations.

The WARPS survey - IV. The X-ray luminosity-temperature relation of high-redshift galaxy clusters [PDF]

, 2000
We present a measurement of the cluster X-ray luminosity–temperature (L–T) relation out to high redshift (z∼0.8). Combined ROSAT PSPC spectra of 91 galaxy clusters detected in the Wide Angle ROSAT Pointed Survey (WARPS) are simultaneously fitted in ...

Chandra X-Ray Analysis of the Massive High-Redshift Galaxy Clusters Cl J1113.1–2615 and Cl J0152.7–1357 [PDF]

, 2003
We present an analysis of Chandra observations of two high-redshift clusters of galaxies, Cl J1113.1-2615 at z = 0.725 and Cl J0152.7-1357 at z = 0.833.

A Lower Bound of Star Formation Activity in Ultra-high-redshift Galaxies Detected with JWST: Implications for Stellar Populations and Radiation Sources [PDF]

Astrophysical Journal Letters, 2022
Early results of James Webb Space Telescope observations have delivered bright z ≳ 10 galaxy candidates in greater numbers than expected, enabling construction of rest-frame UV luminosity functions (LFs).

Understanding the non-linear clustering of high-redshift galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2017
We incorporate the non-linear clustering of dark matter halos, as modelled by Jose et al. (2016) into the halo model to better understand the clustering of Lyman break galaxies (LBGs) in the redshift range $z=3-5$. We find that, with this change, the predicted LBG clustering increases significantly on quasi-linear scales ($0.1 \leq r\,/\,h^{-1} \,{\rm ...

THE HUBBLE SPACE TELESCOPE CLUSTER SUPERNOVA SURVEY. II. THE TYPE Ia SUPERNOVA RATE IN HIGH-REDSHIFT GALAXY CLUSTERS [PDF]

, 2010
We report a measurement of the Type Ia supernova (SN Ia) rate in galaxy clusters at 0.9 < z < 1.46 from the Hubble Space Telescope Cluster Supernova Survey. This is the first cluster SN Ia rate measurement with detected z > 0.9 SNe. Finding 8 ± 1 cluster

Evaluating the GeoSnap 13‐μ$$ \mu $$m cutoff HgCdTe detector for mid‐IR ground‐based astronomy

Astronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023
Abstract New mid‐infrared HgCdTe (MCT) detector arrays developed in collaboration with Teledyne Imaging Sensors (TIS) have paved the way for improved 10‐μ$$ \mu $$m sensors for space‐ and ground‐based observatories. Building on the successful development of longwave HAWAII‐2RGs for space missions such as NEO Surveyor, we characterize the first 13‐μ ...
