Near-infrared spectroscopy of stellar populations in nearby spiral galaxies
J. K. Kotilainen, T. Hyvonen, J. Reunanen +1
We present high spatial resolution, medium spectral resolution near-infrared (NIR) H- and K-band long-slit spectroscopy for a sample of 29 nearby (z < 0.01) inactive spiral galaxie…

Black Holes in Active Galactic Nuclei
M. J. Valtonen, S. Mikkola, D. Merritt +7
Supermassive black holes are common in centers of galaxies. Among the active galaxies, quasars are the most extreme, and their black hole masses range as high as to $6\cdot 10^{10}…

The luminous host galaxies of high redshift BL Lac objects
J. K. Kotilainen, T. Hyvonen, R. Falomo
(abridged) We present near-infrared Ks-band imaging of 13 high redshift (0.6 < z < 1.3) BL Lac objects. We clearly detect the host in eight objects, and marginally in three others.…
