The Baryonic Tully–Fisher Relation. I. WISE/Spitzer Photometry

The Astronomical Journal
We present Wide-field Infrared Survey Explorer (WISE) W1 photometry of the Spitzer Photometry and Accurate Rotation Curves sample. The baseline of near-IR fluxes is established for use by stellar mass models, a key component to the baryonic Tully–Fisher ...

Improved constraints on type Ia supernova host galaxy properties using multi-wavelength photometry and their correlations with supernova properties [PDF]

, 2011
We improve estimates of the stellar mass and mass-weighted average age of Type Ia supernova (SN Ia) host galaxies by combining UV and near-IR photometry with optical photometry in our analysis.

From Halos to Galaxies. X. Decoding Galaxy SEDs with Physical Priors and Accurate Star Formation History Reconstruction

The Astrophysical Journal
The spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional methods, including both parametric and nonparametric approaches, often fail to ...

Galaxy and Mass Assembly: FUV, NUV, ugrizYJHK Petrosian, Kron and Sérsic photometry

, 2011
In order to generate credible 0.1–2 μm spectral energy distributions, the Galaxy and Mass Assembly (GAMA) project requires many gigabytes of imaging data from a number of instruments to be reprocessed into a standard format. In this paper, we discuss the

The Dark Energy Survey Supernova Program: Light Curves and 5 Yr Data Release

The Astrophysical Journal
We present griz photometric light curves for the full 5 yr of the Dark Energy Survey Supernova (DES-SN) program, obtained with both forced point-spread function photometry on difference images ( DiffImg ) performed during survey operations, and scene ...

Improving star-galaxy separation and galaxy group catalogues with multi-band photometry

This thesis focuses on the refinement of an existing and upcoming extragalactic spectroscopic survey by incorporating panchromatic imagery. In particular, we focus on improving the retrieval of galaxy group properties from the GAMA survey, and prepare ...

Exposing Line Emission: The Systematic Differences of Measuring Galaxy Stellar Masses with JWST NIRCam Medium versus Wide Band Photometry

The Astrophysical Journal Letters
Photometrically derived stellar masses are known to suffer from systematic uncertainties, particularly due to nebular emission contributions to the spectral energy distribution (SED).
