Symposium - International Astronomical Union, 1964 The title which the organizers of the Symposium have suggested for this introductory report covers an enormous domain. Even if one limits oneself, as I intend to do, to the large-scale structure, it is impossible to summarize this adequately in one communication.

Spiral structure of our Galaxy and of other galaxies [PDF]
Symposium - International Astronomical Union, 1970 Time and again Dr. B. Bok publishes his reviews on the state of optical searches of the spiral arms in our Galaxy. A great optimist at the beginning, concerning the agreement of different results, he became later more critical in his conclusions. But in his paper of 1967 he claims anew, as well established, that we can trace the spiral arms up to a ...

Spiral structure in external galaxies [PDF]
Symposium - International Astronomical Union, 1970 The need for observing at least four different categories of optical objects for a satisfactory definition of optical spiral structure is emphasized. A sequence of optical form-types for the description of spiral structure is outlined. A pronounced difference in the nature of the spiral structure of the outer and inner parts of Messier 33 is ...

The Evolution of Galaxy Structure Over Cosmic Time [PDF]
Annual Review of Astronomy and Astrophysics, 2014 I present a comprehensive review of the evolution of galaxy structure in the Universe from the first galaxies currently observable at z ∼ 6 down to galaxies observable in the local Universe.

The Galaxy Structure-Redshift Relationship [PDF]
, 2004 There exists a gradual, but persistent, evolutionary effect in the galaxy popu-lation such that galaxy structure and morphology change with redshift. This galaxy structure-redshift relationship is such that an increasingly large fraction of all bright ...

Panic! at the Disks: First Rest-frame Optical Observations of Galaxy Structure at z > 3 with JWST in the SMACS 0723 Field [PDF]
Astrophysical Journal Letters, 2022 We present early results regarding the morphological and structural properties of galaxies seen with the James Webb Space Telescope (JWST) at z > 3 in the Early Release Observations toward the SMACS 0723 cluster field.

CEERS Key Paper. III. The Diversity of Galaxy Structure and Morphology at z = 3–9 with JWST [PDF]
Astrophysical Journal Letters, 2022 We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z = 3–9 using early James Webb Space Telescope (JWST) CEERS NIRCam observations. Our sample consists of 850 galaxies at z

WISDOM Project - X. The morphology of the molecular ISM in galaxy centres and its dependence on galaxy structure [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We use high-resolution maps of the molecular interstellar medium (ISM) in the centres of eighty-six nearby galaxies from the millimetre-Wave Interferometric Survey of Dark Object Masses (WISDOM) and Physics at High Angular Resolution in Nearby GalaxieS

The Distribution of Open Clusters in the Galaxy
Frontiers in Astronomy and Space Sciences, 2021 In this work we explore the new catalog of galactic open clusters that became available recently, containing 1,750 clusters that have been re-analyzed using the Gaia DR2 catalog to determine the stellar memberships.
