Summary
| Description |
English: The active nucleus and some glowing outflows associated with it in the galaxy Markarian 78. I worked together with Dr. Mitchell Revalski on this one. Together I feel like we were able to pick the right datasets to really eke out as much detail as possible for the ionized (glowing) outflows, which are shown in blue. There were some old FOC data in the archive that I myself was too skeptical to try using, but after some encouragement from Mitch it turned out it was actually the best. Other noticeable features include dark dust, shown here in dark brown and orange colors.
Anyway, this may seem like a meager offering compared to other imagery from Hubble, but it's safe to say it's currently the best image (as of this writing) of Mrk 78's nucleus. An arXiv link to the paper on this object is here! arxiv.org/abs/2101.06270 Data from the following proposals were used to create this image. Two proposals from the late 90's and one from 2019. Glad the archive is so well maintained that it is possible to easily combine chronologically disparate datasets. archive.stsci.edu/proposal_search.php?mission=hst&id=... archive.stsci.edu/proposal_search.php?mission=hst&id=... archive.stsci.edu/proposal_search.php?mission=hst&id=... This ended up being a two color orange/cyan image, and the cyan channel is a bit unusual, comprised of data combined from the STIS/CCD 50CCD filter and FOC/96 F502M filter. Neither dataset provided full coverage, so each image makes up for what is missing in the other, and what features showed up in both were similar enough to create a smooth and coherent image despite being from totally different instruments and not quite similar filters. Orange: ACS/WFC F814W Cyan: STIS/CCD 50CCD + FOC/96 F502M North is up. |
