Overview

The ionizing radiation generated by accreting supermassive black holes (SMBHs) can drive powerful outflows of gas that play a key role in galaxy evolution. These outflows are observed on a variety of spatial scales, including in the narrow line regions (NLRs) of AGN on scales of parsecs to kiloparsecs from the SMBH. These outflows can be accurately characterized using the high spatial-resolution imaging and spectroscopy afforded by HST. The team provides new [O III] and continuum images of 12 Seyfert galaxies with existing long-slit HST STIS spectra. The sample spans a moderate range in luminosity, black hole mass, and Eddington ratio, allowing the dependence of outflow parameters on AGN properties to be explored. These High Level Science Products increase the legacy value of the archival STIS spectra by providing matching [O III] images for NLR studies. The products include science images with plate scales of 0.04 arcsec/pixel with north up and east to the left.

Data Products

Data file naming convention:

hlsp_nlr-agn_hst_wfc3_<target>_<filter>_v1_drz.fits

where:

  • <target> is the name of the active galaxy (e.g., "ngc5135")
  • <filter> is one of
    • "f547m" = F547M filter, the emission-line free continuum image
    • "fq508n" = FQ508N filter, the emission-line narrow-band image
    • "f502n" = F502N filter, the emission-line narrow-band image
    • "multi-oiii" = multiple filters, the continuum-subtracted [O III] emission line image

Data file types:

_drz.fits Drizzled science image for the given filter

Data Access

MAST Portal and Astroquery

All observations are available in the MAST Portal and astroquery. Set the 'Provenance Name' filter to NLR-AGN in the Portal Advanced Search to match all observations. The DRZ images can be downloaded for each target as a bundle or individually retrieved by selecting the download basket. The observations can also be retrieved programmatically using the astroquery.mast module. The code example below retrieves all products.

from astroquery.mast import Observations
all_obs = Observations.query_criteria(provenance_name="nlr-agn")
data_products = Observations.get_product_list(all_obs)
Observations.download_products(data_products)
  • A web-based interface for cross-mission searches of data at MAST or the Virtual Observatory.
  • Search for and download NLR-AGN data products programmatically in Python.
