Kraemer Catholic University of America N CoI: Dr. Valentina Braito Catholic University of America N ------------------------------------------------------------------------------------ Abstract MCG-03-34-64 is a nearby Seyfert galaxy with extremely heavy X-ray absorption that makes it one of the hardest sources in the X-ray sky. Consequently this is a superb candidate for study of the faint, extended, circumnuclear X-ray emission. Chandra imaging results for other nearby Compton-thick AGN show structure on a scale of hundreds of pc coincident with the Narrow Line Region gas. Following on from those successful observations we request a 50 ks ACIS-S exposure to trace out the line emitting regions in MCG-03-34-64. We also ask for an HST orbit to map [Oiii] for comparison with the X-ray extent. ------------------------------------------------------------------------------------ Observations Description ------------------------ The acquisition of the HST ACS/WFC [O III]5007A image for MCG -03-34-64 need not be simultaneous and we simply request that this accompanying exposure be within cycle 22. Thus the Joint Observation imposes no constraint on the Chandra scheduling. For HST, as our target has a redshift of z = 0.0165, we will use the FR505N ramp filter. We also propose to obtain a continuum image, to subtract the continuum contribution from the emission line image. We chose FR647M, with which we can select a region free from emission lines. We estimate exposure times based previous observations of sources of similar [Oiii] flux and redshift, where we find a typical 3 sigma surface brightnesses of ~ 10^-15 erg s^ -1 cm^-2 arcsec ^-2 . To reach this sensitivity, we will require an [O III] exposure of ~ 30 minutes. Based on the archival images, for the continuum images we will use 5 minutes of integration. The observations will be split into at least 2 exposures per band, to better eliminate cosmic rays, and apply drizzle patterns. Therefore, the imaging will require 1 orbit in total. ------------------------------------------------------------------------------------ 16847( 2) - 27-Sep-2021 12:35:03 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 MCG-03-34-06 GALAXY, SEYFERT RA=13H22M24.4850S, J2000 V = 12.2 4 DEC=-16D43'42.09" Reference Frame: Other: SIMBAD Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
