"GiGa": the Billion Galaxy HI Survey -- Tracing Galaxy Assembly from Reionization to the Present

open access: yes, 2008
In this paper, we review the Billion Galaxy Survey that will be carried out at radio--optical wavelengths to micro--nanoJansky levels with the telescopes of the next decades.

A Comparison of One-dimensional and Three-dimensional Exoplanet Atmosphere Model Grids: ScCHIMERA and the SPARC/MiTgcm

open access: yesThe Astrophysical Journal
Inferring the properties of transiting exoplanet atmospheres relies on comparing models to spectroscopic observations. Atmosphere models, however, make a range of assumptions, from one-dimensional (1D, varying with altitude) radiative-convective ...

The James Webb Space Telescope: Mission Overview and Status [PDF]

open access: yes
The James Webb Space Telescope (JWST) is the scientific successor to the Hubble Space Telescope. It is a cryogenic infrared space observatory with a 25 m2 aperture (6 m class) telescope that will achieve diffraction limited angular resolution at a ...

Observing Exoplanets with the James Webb Space Telescope [PDF]

open access: yes, 2011
The search for exoplanets and characterization of their properties has seen increasing success over the last few years. In excess of 500 exoplanets are known and Kepler has approx. 1000 additional candidates.

CORINOS. IV. Quantifying Baseline-fitting Uncertainties in SO2 Ice Measurements with JWST/MIRI

open access: yesThe Astrophysical Journal
Sulfur dioxide (SO _2 ) ice has been tentatively detected in protostellar envelopes, but its reliability as a solid-state sulfur reservoir remains unclear.

An Extremely Low-density Exoplanet Spins Slow

open access: yesThe Astrophysical Journal Letters
We present constraints on the shape of Kepler-51d, which is a superpuff with a mass ∼6 M _⊕ and a radius ∼9 R _⊕ , based on detailed modeling of the transit light curve from James Webb Space Telescope (JWST) NIRSpec. The projected shape of this extremely

JWST Near-infrared Spectroscopy of High-albedo Jupiter Trojans: A New Surface Type in the Trojan Belt

open access: yesThe Planetary Science Journal
We present 0.8–5 μ m JWST spectra of four  ~20 km diameter Jupiter Trojans known to have albedos elevated above the values typical in the remaining Trojan population.
