A panchromatic spatially resolved analysis of nearby galaxies – I. Sub-kpc-scale main sequence in grand-design spirals [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We analyse the spatially resolved relation between stellar mass (M⋆) and star formation rate (SFR) in disc galaxies (i.e. the main sequence, MS). The studied sample includes eight nearby face-on grand-design spirals, e.g. the descendant of high-redshift, rotationally supported star-forming galaxies.

, 2000 Two dimensional Fourier spectra of near-infrared images of galaxies provide a powerful diagnostic tool for the detection of spiral arm modulation in stellar disks. Spiral arm modulation may be understood in terms of interference patterns of outgoing and incoming density wave packets or modes.

Spiral arm amplitude variations and pattern speeds in the grand design galaxies M51, M81, and M100
The Astrophysical Journal, 1989 In the modal theory of galactic spiral structure, the amplitude of a prominent two-arm spiral pattern should oscillate slightly with galactocentric distance because of an interference between the outward and inward propagating waves. In the stellar dynamical theory, the spiral arm amplitudes should oscillate because of differential crowding near and ...

THE PdBI ARCSECOND WHIRLPOOL SURVEY (PAWS). I. A CLOUD-SCALE/MULTI-WAVELENGTH VIEW OF THE INTERSTELLAR MEDIUM IN A GRAND-DESIGN SPIRAL GALAXY [PDF]
The Astrophysical Journal, 2013 The PdBI (Plateau de Bure Interferometer) Arcsecond Whirlpool Survey (PAWS) has mapped the molecular gas in the central ~9kpc of M51 in its 12CO(1-0) line emission at cloud-scale resolution of ~40pc using both IRAM telescopes. We utilize this dataset to quantitatively characterize the relation of molecular gas (or CO emission) to other tracers of the ...

PANORAMIC: Discovery of an ultra-massive grand-design spiral galaxy at z∼5.2 [PDF]
Astronomy & AstrophysicsWe report the discovery of an ultra-massive grand-design red spiral galaxy, named Zhúlóng (Torch Dragon), at zphot = 5.2−0.2+0.3 in the JWST PANORAMIC survey; it is the most distant bulge+disk galaxy candidate with spiral arms known to date. Zhúlóng displays an extraordinary combination of properties: (1) a classical bulge centered in a large, face-on ...

HI and CO spectroscopy of the unusual host of GRB 171205A: A grand design spiral galaxy with a distorted HI field [PDF]
GRBs produced by the collapse of massive stars are usually found near the most prominent star-forming regions of star-forming galaxies. GRB 171205A happened in the outskirts of a spiral galaxy, a peculiar location in an atypical GRB host. In this paper we present a highly-resolved study of the molecular gas of this host, with CO(1-0) observations from ...

On donne les profils azimutaux et les diagrammes couleur-amplitude des bras spiraux. On discute des modeles d'evolution de la couleur. Ces modeles sont utilises pour determiner l'amplitude des spirales de densite stellaire sous jacentes et le renforcement ...
