Using camera traps to estimate ungulate abundance: a comparison of mark–resight methods
Remote Sensing in Ecology and Conservation, 2022 Many global wildlife populations are experiencing unprecedented declines. Estimates of population abundance are needed to effectively manage common species and to conserve vulnerable species.

The Panchromatic Hubble Andromeda Treasury. XXI. The Legacy Resolved Stellar Photometry Catalog
The Astrophysical Journal Supplement Series, 2023 We present the final legacy version of stellar photometry for the Panchromatic Hubble Andromeda Treasury (PHAT) survey. We have reprocessed all of the Hubble Space Telescope Wide Field Camera 3 and Advanced Camera for Surveys near-ultraviolet (F275W ...

Stellar Cluster Fiducial Sequences with the Advanced Camera for Surveys [PDF]
The Astronomical Journal, 2005 We present color-magnitude diagrams of five Galactic globular clusters and one Galactic open cluster spanning a wide range of metallicity (-2.1 < [Fe/H] < +0.3), as observed in the F606W (broad V) and F814W (I) bands with the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope.

Virgo’s Intracluster Globular Clusters as Seen by the Advanced Camera for Surveys [PDF]
The Astrophysical Journal, 2007 We report the discovery of 4 candidate intracluster globular clusters (IGCs) in a single deep HST ACS field of the Virgo Cluster. We show that each cluster is roughly spherical, has a magnitude near the peak of the Virgo globular cluster luminosity function, has a radial profile that is best-fit by a King model, and is surrounded by an excess of point ...

An Open Standard for Camera Trap Data
Biodiversity Data Journal, 2016 Camera traps that capture photos of animals are a valuable tool for monitoring biodiversity. The use of camera traps is rapidly increasing and there is an urgent need for standardization to facilitate data management, reporting and data sharing.

The Disturbed and Globular-cluster-rich Ultradiffuse Galaxy UGC 9050-Dw1
The Astrophysical Journal Letters, 2023 We investigate the ultradiffuse galaxy (UDG) UGC 9050-Dw1, which was selected because of its disturbed morphology as part of a larger sample of UDGs that display evidence for significant interactions.
