چکیده
We select 456 gas-star kinematically misaligned galaxies from the internal Product Launch-10 of MaNGA survey, including 74 star-forming (SF), 136 green-valley (GV) and 206 quiescent (QS) galaxies. find that distributions difference between gas star position angles for have three local peaks at $\sim0^{\circ}$, $90^{\circ}$, $180^{\circ}$. The fraction $\log(M_*/M_{\odot})\sim10.5$ declines to both low high mass end. This decreases monotonically with increasing SFR sSFR. compare global parameters kinematic asymmetry $V_{\mathrm{asym}}$, HI detection rate molecular gas, effective radius $R_e$, S\'{e}rsic index $n$ as well spin parameter $\lambda_{R_e}$ their control samples. lower fraction, smaller size, higher than SF GV are more asymmetric in velocity fields controls. These observational evidences point accretion scenario followed by angular momentum redistribution gas-gas collision, leading inflow central formation propose possible origins QS galaxies: (1) external accretion; (2) merger; (3) evolve into

Kinematically Lopsided Spiral Galaxies
Asymmetries in the distribution of light and neutral hydrogen are often observed in spiral galaxies. Here, attention is drawn to the presence of large-scale asymmetries in their kinematics. Two examples of kinematically lopsided galaxies are presented and discussed. The shape of the rotation curve –rising more steeply on one side of the galaxy than on the other– is the signature of the kinemati...
متن کاملSpectral Synthesis of SDSS Galaxies
We investigate the power of spectral synthesis as a mean to estimate physical properties of galaxies. Spectral synthesis is nothing more than the decomposition of an observed spectrum in terms of a superposition of a base of simple stellar populations of various ages and metallicities (here from Bruzual & Charlot 2003), producing as output the star-formation and chemical histories of a galaxy, ...
متن کاملMisaligned Discs as Obscurers in Active Galaxies
We review critically the evidence concerning the fraction of Active Galactic Nuclei (AGN) which appear as Type 2 AGN, carefully distinguishing strict Type 2 AGN from both more lightly reddened Type 1 AGN, and from low excitation narrow line AGN, which may represent a different mode of activity. Low excitation AGN occur predominantly at low luminosities; after removing these, true Type 2 AGN rep...
متن کاملWhy are AGN and Host Galaxies Misaligned?
It is well established observationally that the characteristic angular momentum axis on small scales around active galactic nuclei (AGN), traced by radio jets and the putative torus, is not well correlated with the large-scale angular momentum axis of the host galaxy. In this paper, we show that such misalignments arise naturally in high-resolution simulations in which we follow angular momentu...
متن کاملWarped Galaxies from Misaligned Angular Momenta
A galaxy disk embedded in a rotating halo experiences a dynamical friction force which causes it to warp when the angular momentum axes of the disk and halo are misaligned. Our fully self-consistent simulations of this process induce long-lived warps in the disk that mimic Briggs’s rules of warp behavior. They also demonstrate that random motion within the disk adds significantly to its stiffne...
