Nested Bars with Different Pattern Speeds: NGC 2950
We studied the SB0 galaxy NGC 2950, which hosts two nested stellar bars. We used the Tremaine-Weinberg method to measure the pattern speed of the primary bar...
Net Circular Polarization Of Sunspot Penumbrae - A Versatile Model For Diagnosing Magnetic Field Structure
Sunspot penumbrae harbor highly structured magnetic fields and flows. The moving flux tube model offers an explanation for several observed phenomena, e.g. the...
Neutral and Ionized Atomic Hydrogen Kinematics in the Disk of NGC 3359
We present a kinematical comparison of the HI and HII contents of the barred spiral galaxy NGC 3359. Non-circular motions are observed near the strong bar and...
Neutral and ionized gas dynamics in Blue Compact Dwarf Galaxies
We propose to carry out full-synthesis (12-h) HI ATCA observations of 8 bright Blue Compact Dwarf Galaxies (BCDGs), for which we have already got interesting...
Neutral and ionized gas dynamics in Blue Compact Dwarf Galaxies
We propose to carry out full-synthesis (12-h) HI ATCA observations of 6 bright Blue Compact Dwarf Galaxies (BCDGs). The HIPASS data of these objects indicate...
We study a neutrino gas in equilibrium both at T = 0 and at finite temperature. The neutrinos are assumed to be massive Dirac particles with two generations...
