    Deep NIR J/H/K band imaging for a sample of 20 QSO host galaxies is presented in this paper from the parent sample of CARS. A QSO-host image decomposition was done to measure the mass of the bulge component of the host. This is compared to the BH mass inferred from longslit spectroscopy to probe the BH mass-bulge mass relation. The authors found that most of the bulge are below the local BH mass-bulge mass relation established for inactive galaxies.

  • A low-luminosity type-1 QSO sample: II. Tracing circumnuclear star formation in HE1029-1831 with SINFONI

    G. Busch, S. Smajic, J. Scharwächter, A. Eckart, M. Valencia-M., L. Moser, B. Husemann, M. Kirps, J. Zuther, 2015, A&A, 575, A128

    The paper presents high spatial resolution NIR H+K band IFU observations of the central regions of HE1029-1401 which is also part of the CARS sample and observed with MUSE.

  • HI in nearby low-luminosity QSO host galaxies

    S. König, A. Eckart, M. Garcia-Marin, W. K. Huchtmeier, 2009, A&A, 507, 757

    This paper present HI observations for the majority of CARS galaxies with the 100m Effelsberg single-dish radio telescope. 12 QSO host galaxies have been detected in HI and upper limits are presented for the remaining 15 targets.

  • Molecular gas in nearby low-luminosity QSO host galaxies

    T. Bertram, A. Eckart, S. Fischer, J. Zuther, C. Straubmeier, L. Wisotzki, M. Krips, 2007, A&A, 470, 571

    This paper reports the CO(1-0) and CO(2-1) for a sample of QSO selected from the Hamburg ESO survey at 0.01<z<0.06 to probe their molecular gas content. It represent the basis for the CARS sample.
