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

A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). X. The Massive and Passive Nature of Radio Galaxies at z ∼ 4

The Astrophysical Journal
High- z radio galaxies (HzRGs) are considered important objects for understanding the formation and evolution of massive galaxies in the early Universe.

Infrared photometry and spectrophotometry of Titan [PDF]

The wide variation in infrared brightness temperature of Titan is explained in terms of a greenhouse effect. Radiometric observations in the infrared and microwave frequencies indicate an alternate hot atmospheric model. Methane, ammonia, hydrogen atoms,
