Long-slit spectroscopy of 1000 nearby galaxies

HET massive galaxy survey


I am currently leading the HET Galaxy Survey with the Low Resolution Spectrograph on the 9.2m Hobby-Eberly Telescope at the McDonald Observatory in West-Texas to find all possible galaxies suitable for black hole mass estimates in the Northern Hemisphere. Using more than 550 hours (eqv. 50+ nights) we have obtained long-slit spectra of more than 1016 spirals and ellipticals galaxies to create a census of the Northern galaxies in the local volume (z<0.03). The target selection if primarily based on 2MASS photometry and redshift distances. The survey ended in 2013, when the HET was shutdown for the HETDEX upgrade.

With this survey it is now possible to determine the demographics of the black hole population in the galaxies in the local volume. The figure shows the distribution of observed galaxies in a equatorial projection.

The survey presentation and data set is available as a preprint. Comments and suggestions welcome.

The v0.0 of the data products are also available. Plots of the spectral fits and the stellar kinematics are all available

The raw and reduced data are also freely available. However due to the large size of the dataset it is not directly linked here. Hopefulyl this will be resolved soon. If you want a copy of (any) of the data, please send an email.
