New Photometric Calibration of the Wide Field Camera 3 Detectors
A. Calamida, V. Bajaj, J. Mack +6
We present a new photometric calibration of the WFC3-UVIS and WFC3-IR detectors based on observations collected from 2009 to 2020 for four white dwarfs, namely GRW+70~5824, GD~153,…
The Orbit of the Close Companion of Polaris: Hubble Space Telescope Imaging 2007 to 2014
Nancy Remage Evans, Margarita Karovska, Howard E. Bond +6
As part of a program to determine dynamical masses of Cepheids, we have imaged the nearest and brightest Cepheid, Polaris, with the Hubble Space Telescope Wide Field Planetary Came…
The Frontier Fields: Survey Design

A New Hubble Space Telescope Distance to NGC 1569: Starburst Properties and IC 342 Group Membership
Aaron J. Grocholski, Alessandra Aloisi, Roeland P. van der Marel +8
We present deep HST ACS/WFC photometry of the dwarf irregular galaxy NGC 1569, one of the closest and strongest nearby starburst galaxies. These data allow us, for the first time,…
Do young galaxies exist in the Local Universe? - Red Giant Branch detection in the metal-poor dwarf SBS 1415+437
A. Aloisi, R. P. van der Marel, J. Mack +3
We present results from an HST/ACS imaging study of the metal-poor blue compact dwarf galaxy SBS 1415+437. It has been argued previously that this is a very young galaxy that start…
