High-z Stellar Masses Can Be Recovered Robustly with JWST Photometry

open access: yesThe Astrophysical Journal Letters
Robust inference of galaxy stellar masses from photometry is crucial for constraints on galaxy assembly across cosmic time. Here, we test a commonly used spectral energy distribution (SED) fitting code using simulated galaxies from the S phinx ^20 ...

 photometry of the resolved dwarf galaxy Ho IX

open access: yes, 2004
We present BVR CCD photometry down to limiting magnitude $B=23.5$ mag for 232 starlike objects and 11 diffuse objects in a $5\farcm4 \times 5\farcm4$ field of Ho IX.

Near-infrared photometry of carbon stars in the Sagittarius dwarf irregular galaxy and DDO 210 [PDF]

open access: yes, 2007
Aims.We investigate the intermediate-age asymptotic giant branch stellar population of two Local Group dwarf irregular galaxies to characterize their carbon star population in near-infrared (IR).

Spectroscopic Confirmation of an Ultra-Massive Galaxy in a Protocluster at $z \sim 4.9$

open access: yesThe Open Journal of Astrophysics
We present spectroscopic confirmation of an ultra-massive galaxy (UMG) with $\log(M_\star/M_\odot) = 10.98 \pm 0.07$ at $z_\mathrm{spec} = 4.8947$ in the Extended Groth Strip (EGS), based on deep observations of Ly$\alpha$ emission with Keck/DEIMOS.

Extended photometry for the DEEP2 Galaxy Redshift Survey: a testbed for photometric redshift experiments

open access: yes, 2013
This paper describes a new catalog that supplements the existing DEEP2 Galaxy Redshift Survey photometric and spectroscopic catalogs with ugriz photometry from two other surveys: the Canada-France-Hawaii Legacy Survey (CFHTLS) and the Sloan Digital Sky ...

The S4G-WISE View of Global Star Formation in the Nearby Universe

open access: yesThe Astrophysical Journal
In this work, we present source-tailored Wide-field Infrared Survey Explorer (WISE) mid-infrared photometry (at 3.4, 4.6, 12, and 23 μ m) of 2812 galaxies in the extended Spitzer Survey of Stellar Structure in Galaxies sample, and characterize the mid ...

Crowded Field Galaxy Photometry: Precision Colors in the CLASH Clusters

open access: yes, 2017
We present a new method for photometering objects in galaxy clusters. We introduce a mode-filtering technique for removing spatially variable backgrounds, improving both detection and photometric accuracy (roughly halving the scatter in the red sequence ...

Galaxy properties from J-PAS narrow-band photometry [PDF]

open access: yes, 2017
We study the consistency of the physical properties of galaxies retrieved from SED-fitting as a function of spectral resolution and signal-to-noise ratio (SNR).

Automated Computer Vision Cluster Identification in the Fireworks Galaxy

open access: yesThe Astrophysical Journal
We present the integrated photometry, radii, and spatial distribution of young (≤25 Myr) star cluster candidates in NGC 6946. NGC 6946, also known as the Fireworks Galaxy, is a highly star-forming galaxy with numerous young massive clusters.
