The CANDELS/SHARDS Multiwavelength Catalog in GOODS-N: Photometry, Photometric Redshifts, Stellar Masses, Emission-line Fluxes, and Star Formation Rates [PDF]

open access: yesAstrophysical Journal Supplement Series, 2019
We present a WFC3 F160W (H-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts, and stellar parameters derived from the analysis of the multiwavelength data ...

Quantitative analysis of inhibitor-induced assembly disruption in human UDP-GlcNAc 2-epimerase using mass photometry. [PDF]

open access: yesProtein Sci
Abstract Uridine diphosphate N‐acetylglucosamine (UDP‐GlcNAc) 2‐epimerase (GNE)/N‐acetylmannosamine kinase is the rate‐limiting enzyme in sialic acid biosynthesis and a promising therapeutic target. We applied mass photometry (MP) to investigate GNE oligomerization and its modulation by three small‐molecule inhibitors (C5, C13, and C15).

Effective temperatures and radii of planet-hosting stars from IR photometry [PDF]

open access: yes, 2003
In this paper we present and analyse determinations of effective temperatures of planet-hosting stars using infrared (IR) photometry. One of our goals is the comparison with spectroscopic temperatures to evaluate the presence of systematic effects that ...

Fixing the U-band photometry of Type Ia supernovae [PDF]

open access: yes, 2012
We present previously unpublished photometry of supernovae 2003gs and 2003hv. Using spectroscopically-derived corrections to the U-band photometry, we reconcile U-band light curves made from imagery with the Cerro Tololo 0.9-m, 1.3-m and Las Campanas 1-m

Deriving Physical Properties from Broadband Photometry with Prospector: Description of the Model and a Demonstration of its Accuracy Using 129 Galaxies in the Local Universe [PDF]

open access: yes, 2016
Broadband photometry of galaxies measures an unresolved mix of complex stellar populations, gas, and dust. Interpreting these data is a challenge for models: many studies have shown that properties derived from modeling galaxy photometry are uncertain by

Galaxy surface photometry [PDF]

open access: yes, 1999
We describe galaxy surface photometry based on fitting ellipses to the isophotes of the galaxies. Example galaxies with different isophotal shapes are used to illustrate the process, including how the deviations from elliptical isophotes are quantified ...

Overview of Gaia Multi-Color Photometry

open access: yesOpen Astronomy, 2003
Gaia will obtain multi-color photometry for astrometric and astrophysical purposes. A photometry in five broad bands and with high angular resolution will be obtained after every astrometric observation of a star, especially for the sake of correcting ...

Sobre a Dosagem Fotométrica do Cobre em Águas

open access: yesBrazilian Archives of Biology and Technology, 2001
The author presents an analytic process for copper quantitative determination in mineral and potable waters, based in the reaction of the cation copper with sodium diethyl-dithio carbamate. Due to the presence of certain elements common in water, such as

NORAD TLE Type Orbit Determination of LEO Satellites Using GPS Navigation Solutions [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2002
NORAD Two Line Elements (TLE) are widely used for the increasing number of small satellite mission operations and analysis. However, due to the irregular periodicity of generation of the NORAD TLE, a new TLE that is independent of NORAD is required.
