ESO Programme ID: 60.A-9041 Principal Investigator Name: Harald Kuntschner Principal Investigator E-mail Address: hkuntsch@eso.org Principal Investigator Telephone Number: 6465 Principal Investigator Postal Address: ESO Instrument: Sinfoni OPC Priority Class: SV OPC Approved Total Execution Time: SV Estimated Total Execution Time (including overheads): 5.5h README File Submission Date: 26.09.2004 Programme Description ===================== General Overview ---------------- K-band spectroscopy of the central (3.2x3.2arcsec) regions of a giant elliptical galaxy (NGC1399) in the Fornax cluster will be used to probe the stellar kinematics influenced by a super massive black hole (radius of influence on the order of 1"). The measurement of the central velocity dispersion map and the higher moments of the velocity profile will be used to estimate the black hole mass (e.g., Gebhardt et al. 2003, ApJ, 583, 92). High spatial resolution is of pramaount importance to obtain good black hole mass estimates. Previously, this work was mainly done with STIS spectroscopy, but the AO capabilities of Sinfoni open up a new path to measure black hole masses. NGC1399 is the cD of the Fornax cluster and therefore is expected to agree well with the black hole mass versus velocuty dispersion relation ship. Additionally the K-band CO lines and the weaker Na and Ca lines will be useful to investigate the central stellar populations. Approved Waiver Request Summary ------------------------------- - Critical Observing Condition Constraints ---------------------------------------- - Time Critical Aspects --------------------- - Special Calibration Information ------------------------------- In order to determine the stellar kinematics we require the observations of kinematic template stars (type K5III - M2III). See OBs below which are listed in order of priority. At least three stars of different spectral type are necessary to perform the kinematic analysis. M?III stars are particularly important for this program. PLEASE observe in "bad" seeing conditions to avoid saturation of detector! A good coverage with telluric standard stars is important to allow for the anlysis of the line-strengths indices.

No finding charts for the template stars were submitted. Two reasons: (1) The FC plugin for fims crashed all the time on DSS images. (2) The template stars are very bright compared to any surrounding stars within 10" radius. So easy to identify. List of Calibration OBs with Associated Science OBs --------------------------------------------------- Total Number of Submitted Calibration OBs: 0 OB Compliance Checks ==================== (Y = Yes, N = No, NA = Not Applicable) Do all your OBs comply with the instrument specific requirements listed on the instrument specific Phase 2 Web pages ?
