VizieR Online Data Catalog: Star-forming clumps in local luminous IR galaxies (Larson+, 2020)

The Great Observatories All-Sky LIRG Survey (GOALS; Armus+ 2009PASP..121..559A) is a complete galaxy sample that comprises the 201 LIRG systems (z<0.088) included in the IRAS Revised Bright Galaxy Sample (Sanders+ 2003, J/AJ/126/1607).

Here we present and analyze Paα and Paβ HST images of a sample of 48 LIRGs in GOALS with LIR values that range from 10^11.2 to 10^12.3. The Paα data (27 systems) are HST archival images from PID 10169.

The Paβ observations were taken with the HST WFC3 camera (Project ID: 13690; PI: T. Diaz-Santos), which has a plate scale of 0.12"/pixel using the F130N and F132N narrowband filters and the F110W broadband filter. The total integration times were 120s for each broadband filter and about 1100s (19min) for each narrowband filter. The 2' FOV of WFC3-IR allows for galaxies in a pair to be observed simultaneously.

The archival Paα observations were taken with the HST NIC2 camera, which has a plate scale of 0.076"/pixel and a 19.2" FOV using the F187N and F190N narrowband filters.
