Abstract: (arXiv)
Investigation of gaseous and stellar kinematics and of broad-band VRI and narrow-band H-alpha and [NII]6583 images is performed for the central part (R < 4 kpc) of the regular spiral galaxy NGC 2841. We have found emission-line splitting at R < 20 and three-component LOSVD for the stars in the radius range 6 - 100. Morphological analysis reveals strong narrow shock fronts close to the major axis in the radius range of 30 - 50, a turn of the isophote major axis by 5 degrees and strongly negative Fourier coefficient a4 (boxy isophotes) in the radius range of 15 - 33. In principle, all these features may be explained in the frame of a triaxial bulge hypothesis.References(22)
