The MOST Hosts Survey: Spectroscopic Observation of the Host Galaxies of ∼40,000 Transients Using DESI

The Astrophysical Journal Supplement Series
We present the Multi-Object Spectroscopy of Transient (MOST) Hosts survey. The survey is planned to run throughout the 5 yr of operation of the Dark Energy Spectroscopic Instrument (DESI) and will generate a spectroscopic catalog of the hosts of most ...

The redshifts from 122 bands: Comparative redshift forecast for low-resolution spectra from SPHEREx and the 7-Dimensional Sky Survey (7DS)

Astronomy & Astrophysics
The recently initiated SPHEREx and 7DS surveys will deliver low-resolution spectra (R ∼ 20 − 130) for hundreds of millions of galaxies over the optical to near-infrared range (0.4 − 5.0 μm), covering a wide sky area without sample selection. These unique

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

Advanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Testing the Standard Cosmological Model [PDF]

, 2011
This thesis exploits the wealth of information contained in the existing cosmological surveys, and demonstrates how the use of tools such as two-point statistics permit the extraction of such information.

Bayesian inference from photometric redshift surveys

, 2012
We show how to enhance the redshift accuracy of surveys consisting of tracers with highly uncertain positions along the line of sight. Photometric surveys with redshift uncertainty δz ∼ 0.03 can yield final redshift uncertainties of δz f ∼ 0.003 in high ...

Photometric Redshift Forecast for the 7-Dimensional Sky Survey

The Astrophysical Journal
We 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

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

Advanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

Designing a space-based galaxy redshift survey to probe dark energy

, 2010
A space-based galaxy redshift survey would have enormous power in constraining dark energy and testing general relativity, provided that its parameters are suitably optimized.

Photometric Redshift Systematics In Optical Cosmology Surveys [PDF]

, 2021
Weak lensing cosmology surveys measure the light from distant galaxies as it undergoes a series of distortions, suffering from deflections by both the large scale structure of the universe and individual galaxies.

The TOOT00 redshift survey of radio sources

Astronomische Nachrichten, 2006
AbstractWe present first results from the study of the TOOT00 region consisting of 47 radio sources brighter than 100 mJy at 151 MHz. We have 81% spectroscopic redshift completeness. From theK‐zdiagram we deduce that the host galaxies are similar to ∼ 3L* passively evolved elliptical galaxies and thus estimate the redshifts of the 9 sources without a ...
