The Redshift of GRB 190829A/SN 2019oyw: A Case Study of GRB-SN Evolution

The Astrophysical Journal
The nearby long gamma-ray burst (GRB) 190829A was observed using the Hubble Space Telescope/Wide Field Camera 3/infrared grisms about four weeks to 500 days after the burst.

The nuclear star cluster of M 74: A fossil record of the very early stages of a star-forming galaxy

Astronomy & Astrophysics
Nuclear star clusters (NSC) are dense and compact stellar systems with sizes of a few parsecs located at galactic centers. Their properties and formation mechanisms seem to be tightly linked to the evolution of the host galaxy, with potentially different

The halo magnetic field of a spiral galaxy at z = 0.414

Astronomy & Astrophysics
Aims. Even though magnetic fields play an important role in galaxy evolution, the redshift evolution of galactic-scale magnetic fields is not well constrained observationally.

Detection of CO emission in Hydra 1 cluster galaxies [PDF]

A survey of bright Hydra cluster spiral galaxies for the CO(1-0) transition at 115 GHz was performed with the 15m Swedish-ESO submillimeter telescope (SEST). Five out of 15 galaxies observed have been detected in the CO(1-0) line.

Spiral galaxies

, 1995
This thesis deals with surface photometry of face-on spiral galaxies in a statistical way, using both single passband as well as color information of a large sample of galaxies. In this chapter I first discuss galaxy formation and evolution models and the role that photometry plays in testing these models.

DESI EDR: Calibrating the Tully–Fisher Relationship with the DESI Peculiar Velocity Survey

The Astrophysical Journal
We calibrate the Tully–Fisher relation (TFR) with data from the DESI Peculiar Velocity (PV) Survey taken during the Survey Validation (SV) period of the DESI galaxy redshift survey.

Dissecting Bar-induced Stellar Kinematics in Disk Galaxies: The Bisymmetric Model and Rotation Curve Modifications

The Astrophysical Journal
We analyze bars formed in N -body simulations to investigate two key aspects of stellar kinematic structure of barred galaxies: the angular distributions of the radial and azimuthal components of stellar velocities, and the impact of bars on rotation ...
