Stellar structures, molecular gas, and star formation across the PHANGS sample of nearby galaxies [PDF]
Astronomy & Astrophysics, 2021 We identify stellar structures in the PHANGS sample of 74 nearby galaxies and construct morphological masks of sub-galactic environments based on Spitzer 3.6 micron images.

Rotation and Mass in the Milky Way and Spiral Galaxies [PDF]
, 2016 [PASJ Review Paper] Rotation curves are the basic tool for deriving the distribution of mass in spiral galaxies. In this review, we describe various methods to measure rotation curves in the Milky Way and spiral galaxies.

Galaxy And Mass Assembly (GAMA): stellar mass growth of spiral galaxies in the cosmic web [PDF]
, 2016 We look for correlated changes in stellar mass and star formation rate (SFR) along filaments in the cosmic web by examining the stellar masses and UV-derived SFRs of 1799 ungrouped and unpaired spiral galaxies that reside in filaments. We devise multiple

Symposium - International Astronomical Union, 1970 We point out some properties of barred spiral galaxies which are important for the theory of their formation and spiral structure, and describe some theoretical work on the dynamics of these systems.

Dawes Review 4: Spiral Structures in Disc Galaxies [PDF]
Publications Astronomical Society of Australia, 2014 The majority of astrophysics involves the study of spiral galaxies, and stars and planets within them, but how spiral arms in galaxies form and evolve is still a fundamental problem. Major progress in this field was made primarily in the 1960s, and early

The Global Schmidt law in star forming galaxies [PDF]
, 1997 Measurements of Hα, H I, and CO distributions in 61 normal spiral galaxies are combined with published far-infrared and CO observations of 36 infrared-selected starburst galaxies, in order to study the form of the global star formation law over the full ...

HOT GASEOUS CORONAE AROUND SPIRAL GALAXIES: PROBING THE ILLUSTRIS SIMULATION [PDF]
, 2015 The presence of hot gaseous coronae around present-day massive spiral galaxies is a fundamental prediction of galaxy formation models. However, our observational knowledge remains scarce, since to date only four gaseous coronae have been detected around ...

Accretion, radial flows and abundance gradients in spiral galaxies [PDF]
, 2015 The metal-poor gas continuously accreting on to the discs of spiral galaxies is unlikely to arrive from the intergalactic medium (IGM) with exactly the same rotation velocity as the galaxy itself and even a small angular momentum mismatch inevitably ...

IN-N-OUT: THE GAS CYCLE FROM DWARFS TO SPIRAL GALAXIES [PDF]
, 2015 We examine the scalings of galactic outflows with halo mass across a suite of 20 high-resolution cosmological zoom galaxy simulations covering halo masses in the range .

CHARACTERISTICS OF SPIRAL ARMS IN LATE-TYPE GALAXIES [PDF]
, 2014 We have measured the positions of large numbers of H ii regions in four nearly face-on, late-type, spiral galaxies: NGC 628 (M74), NGC 1232, NGC 3184, and NGC 5194 (M51).
