General Description

Our observations aim at resolving the nuclear star cluster in the bulgeless
 galaxy NGC 3621. 
This is the closest late type, bulgeless galaxy known to host both a nuclear star
 cluster and a confirmed AGN. 
The observations will yield a spatially resolved spectrum of this nuclear star cluster
 from which we will determine its stellar populations and kinematics. Modeling of
 these data will (1) strongly constrain the formation history for this NC, and (2)
 may well provide the first dynamical black hole mass measurement within a bulgeless
 galaxy.

The FLAMES data will be complemented by SINFONI and NACO data.

Target: Nuclear star cluster in NGC 3621
Rmag:   15.7 mag
B-R :    2.1 mag
Kmag:   13.3 mag
FWHM:    approx. 0.3 arcsec

For LR 02 : GS=11.5; FACB=12.6,12.9,12.4,12.4; HA=+-7h, S/N=25@427.2nm
For LR 08 : GS=11.5; FACB=12.6,12.9,12.4,12.4; HA=+-7h, S/N=25@881.7nm

At the beginning and at the end of each OB we included a short exposure with a simultaneous
 Thorium-Argon calibration lamp on top of our target. This is to enable higher radial
 velocity accuracy.
