Gravitational bar and spiral arm torques from Ks-band observations and implications for the pattern speeds
Block, D.L.; Buta, R.J.; Knapen, J.; Elmegreen, D.M.; Elmegreen, B.; Puerari, I. (2004-07) -
The gravitational torque of bar in optically unbarred and barred galaxies
Block, D.L.; Puerari, I.; Knapen, J.; Elmegreen, B.; Buta, R.J.; Stedman, S.; Elmegreen, D.M. (2001-09) -
The Gravitational Torque of Bars
Puerari, I.; Block, D.L.; Knapen, J.; Elmegreen, B.; Buta, R.J.; Stedman, S.; Elmegreen, D.M. (Astronomical Society of the Pacific, 2002)We have determined the gravitational torque of a sample of 45 galaxies observed at K band with the 4.2m William Herschel Telescope. The results of this sample, combined with those for a sample of 30 galaxies previously ... -
MUSE stares into the shadows: the high-resolution dust attenuation curve of NGC 5626
Viaene, S.; Sarzi, M.; Baes, M.; Fritz, J.; Puerari, I. (2017-12-01)The newest generation of integral field unit spectrographs brings three-dimensional mapping of nearby galaxies one step closer. While the focus up to this point was mostly on stars and ionized gas, it is also possible to ... -
NGC 5626: a massive fast rotator with a twist
Viaene, S.; Sarzi, M.; Baes, M.; Puerari, I. (2018-02-11)We present a kinematic analysis of the dust-lane elliptical NGC 5626 based on MUSE observations. These data allow us to robustly classify this galaxy as a fast rotator and to infer a virial mass of 10 11.7M⊙, making it one ... -
Penetrating the Mask: All Spiral Galaxies become barred on bar torque scales between zero and six
Block, D.L.; Buta, R.J.; Puerari, I.; Knapen, J.; Elmegreen, B.; Stedman, S.; Elmegreen, D.M. (2002)
