Orbital structure of triaxial galaxies [PDF]
Symposium - International Astronomical Union, 2004 We have developed a method to construct realistic triaxial dynamical models for elliptical galaxies, allowing us to derive best-fitting parameters, such as the mass-to-light ratio and the black hole mass, and to study the orbital structure. We use triaxial theoretical Abel models to investigate the robustness of the method.

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis
Hepatology, EarlyView., 2022 Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

Vertical Density Distribution of the Galaxy from Star Count Analysis [PDF]
Journal of Astronomy and Space Sciences, 2002 The five space density distribution D(z) with distance perpendicular to the Galactic plane were combined. The scale heights and the local densities at z = 0 of the thin disk, thick disk, and the halo components were estimated from the nonlinear least ...

Molecular Structures of Other Galaxies Compared to That of the Galaxy [PDF]
Symposium - International Astronomical Union, 1979 Of the eleven galaxies with detected CO emission, eight have bright nuclear CO sources: M82, NGC 253, M51, NGC 5236, NGC 1068, Maffei 2 (Rickard et al. 1977a,b), NGC 6946, and IC 342 (Morris and Lo 1978). Two have disk-population CO sources and no detectable nuclear source (M31 and M81, Combes et al. 1977a), and one has no obvious nucleus (LMC, Huggins,

The transformation of Spirals into S0 galaxies in the cluster environment
Frontiers in Astronomy and Space Sciences, 2015 We discuss the observational evidences of the morphological transformation of Spirals into S0 galaxies in the cluster environment exploiting two big databases of galaxy clusters: WINGS (0 ...

Gravitational Lenses and the Structure of Galaxies [PDF]
Symposium - International Astronomical Union, 1996 Nearly singular isothermal mass distributions with small core radii are consistent with stellar dynamics, lens statistics, and lens models as a model for E/S0 galaxies. Models like the de Vaucouleurs model with a constant mass-to-light ratio are not.

The Astrophysical Journal, 2023 We study the morphological properties of mid-infrared selected galaxies at 1.0 < z < 1.7 in the SMACS J0723.3-7327 cluster field to investigate the mechanisms of galaxy mass assembly and structural formation at cosmic noon.

The Origin of Star-forming Rings in S0 Galaxies
The Astrophysical Journal, 2023 Spatially resolved integral field spectroscopic maps in a sample of 532 S0 galaxies from the MaNGA survey have unveiled the existence of inner rings (〈 R 〉 ∼ 1 R _e ) betraying ongoing star formation in a number of these objects.

The Complex Structure of the Bulge of M31
The Astrophysical Journal Supplement Series, 2023 The bulge of M31 is of interest regarding the nature of galactic bulges and how their structure relates to bulge formation mechanisms and their subsequent evolution.
