The Advanced Camera for Surveys Fornax Cluster Survey. VII. Half-light Radii of Globular Clusters in Early-type Galaxies [PDF]

open access: bronze, 2010
We measure the half-light radii of globular clusters (GCs) in 43 galaxies from the Advanced Camera for Surveys (ACS) Fornax Cluster Survey. We use these data to extend previous work in which the environmental dependencies of the half-light radii of GCs ...

GEMS Survey Data and Catalog [PDF]

open access: yes, 2008
We describe the data reduction and object cataloging for the GEMS survey, a large-area (800 arcmin(2)) two-band (F606W and F850LP) imaging survey with the Advanced Camera for Surveys on the Hubble Space Telescope, centered on the Chandra Deep Field-South.

A novel ddPCR™ assay for eDNA detection and quantification of Greater Amberjack Seriola dumerilli and three congeners in US waters: challenges and application to fisheries independent surveys [PDF]

open access: yesPeerJ
Background Four Seriola species support recreational and commercial fisheries along the U.S. Atlantic Ocean and the Gulf of Mexico, with the S. dumerili Gulf of Mexico stock being overfished for over three decades.

Optimal multihump filter for photometric redshifts [PDF]

open access: yes, 2001
We propose a novel type filter for multicolor imaging to improve on the photometric redshift estimation of galaxies. An extra filter - specific to a certain photometric system - may be utilized with high efficiency.

The Hubble Space Telescope Advanced Camera for Surveys Emission Line Survey of Andromeda. I. Classical Be Stars [PDF]

open access: yesThe Astronomical Journal, 2020
Abstract We present results from a two epoch Hubble Space Telescope Hα emission line survey of the Andromeda galaxy that overlaps the footprint of the Panchromatic Hubble Andromeda Treasury (PHAT) survey. We found 552 (542) classical Be stars and 8429 (8556) normal B-type stars in epoch # 1 (epoch # 2), yielding an overall fractional Be ...

The far-ultraviolet main auroral emission at Jupiter – Part 2: Vertical emission profile [PDF]

open access: yesAnnales Geophysicae, 2015
The aurorae at Jupiter are made up of many different features associated with a variety of generation mechanisms. The main auroral emission, also known as the main oval, is the most prominent of them as it accounts for approximately half of the total ...

A New Galaxy Cluster Merger Capable of Probing Dark Matter: A56

open access: yesThe Astrophysical Journal, 2023
We report the discovery of a binary galaxy cluster merger via a search of the redMaPPer optical cluster catalog, with a projected separation of 535 kpc between the brightest cluster galaxies (BCGs).
