The Baryonic Tully–Fisher Relation. II. Stellar Mass Models

The Astronomical Journal
We present new color–ϒ _* (mass-to-light ratio) models to convert Wide-field Infrared Survey Explorer W1 fluxes into stellar masses. We outline a range of possible star formation histories and chemical evolution scenarios to explore the confidence limits

Bright z ∼ 9 Galaxies in Parallel: The Bright End of the Rest-frame UV Luminosity Function from HST Parallel Programs

The Astrophysical Journal
The abundance of bright galaxies at z > 8 can provide key constraints on models of galaxy formation and evolution, as the predicted abundance varies greatly when different physical prescriptions for gas cooling and star formation are implemented.

Diversity of Cold Worlds: A Near-complete Spectral Energy Distribution for 2MASS J04151954−0935066 Using JWST

The Astrophysical Journal
We present a near-complete spectral energy distribution (SED) for an extrasolar world: the T8 brown dwarf 2MASS J04151954−0935066. Spanning from optical to mid-infrared (0.7–20.4 μ m) wavelengths, the SED for this substellar atmosphere is constructed ...

Spitzer Space Telescope observations of hot Jupiters [PDF]

, 2015
Currently the Spitzer Space Telescope is the most reliable telescope for conducting secondary eclipse observations of exoplanets. The depth and the time of mid-eclipse are two important parameters that come from a secondary eclipse analysis. The eclipse depth gives information on the temperature of the atmosphere, and can provide evidence for the ...
