RotCurves: A PYTHON package for efficient modelling and fitting of galactic rotation curves at high-z

A. Nestor Shachar, A. Sternberg, S. H. Price +18

Rotation curves are a fundamental tool in the study of galaxies across cosmic time, and with the advent of large integral field unit (IFU) kinematic surveys there is an increasing…

Gasflows in Barred Galaxies with Big Orbital Loops-A Comparative Study of Two Hydrocodes

Stavros Pastras, Panos A. Patsis, E. Athanassoula

We study the flow of gas in a barred-galaxy model, in which a considerable part of the underlying stable periodic orbits have loops where, close to the ends of the bar, several orb…

Morphologies arising from the gas flow in the innermost kiloparsec of barred galaxy models

Stavros Pastras, Panos A. Patsis, E. Athanassoula

Context. We study a series of response models to investigate the formation of specific morphological features in the central 1 kpc region of the gas component in barred spiral gala…

NOEMA: A first kpc resolution study of a main sequence barred galaxy channeling gas into a growing bulge

Stavros Pastras, Reinhard Genzel, Linda J. Tacconi +32

We present a very deep CO(3-2) observation of a massive, gas-rich, main sequence, barred spiral galaxy at . Our data were taken with the IRAM-NOEMA interferometer for…

Galaxy morphologies at cosmic noon with JWST: A foundation for exploring gas transport with bars and spiral arms

Juan M. Espejo Salcedo, Stavros Pastras, Josef Vácha +22

The way in which radial flows shape galaxy structure and evolution remains an open question. Internal drivers of such flows, such as bars and spiral arms, known to mediate gas flow…

A large-scale ring galaxy at z = 2.2 revealed by JWST/NIRCam: kinematic observations and analytical modelling

A. Nestor Shachar, A. Sternberg, R. Genzel +24

A unique galaxy at z = 2.2, zC406690, has a striking clumpy large-scale ring structure that persists from rest UV to near-infrared, yet has an ordered rotation and lies on the star…
