Cosmology and perturbations in tachyonic massive gravity

Kavli Affiliate: Lijing Shao | First 5 Authors: Amin Rezaei Akbarieh, Sobhan Kazempour, Lijing Shao, , | Summary: As massive gravity and its extensions offer physically well-defined gravitational theories with a nonzero graviton mass, we present a new extension of the de Rham-Gabadadze-Tolley (dRGT)massive gravity, which is tachyonic massive gravity theory. We firstly introduce the […]

Strong spiral arms drive secular growth of pseudo bulges in disk galaxies

Kavli Affiliate: Jing Wang | First 5 Authors: Si-Yue Yu, Dewang Xu, Luis C. Ho, Jing Wang, Wei-Bo Kao | Summary: Spiral-driven instabilities may drive gas inflow to enhance central star formation in disk galaxies. We investigate this hypothesis using the Sloan Digital Sky Survey (SDSS) in a sample of 2779 nearby unbarred star-forming main-sequence […]

Evidence for quasar fast outflows being accelerated at the scale of tens of parsecs

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhicheng He, Guilin Liu, Tinggui Wang, Guobin Mou, Richard Green | Summary: Quasar outflows may play a crucial role in regulating the host galaxy, although the spatial scale of quasar outflows remain a major enigma, with their acceleration mechanism poorly understood. The kinematic information of outflow […]
