THE CANADA-FRANCE REDSHIFT SURVEY IX: HST Imaging of High-Redshift Field Galaxies

open access: yes, 1995
HST B and I images are presented of 32 CFRS galaxies with secure redshifts in the range 0.5 < z < 1.2. These galaxies exhibit the same range of morphological types as seen locally, i.e., ellipticals, spirals and irregulars.

Triazine‐Trione Thermosets with High Processability for Scaffold Applications in Bone Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

Modeling the Radial Color Profile of M31

open access: yesOpen Astronomy, 2003
We present a preliminary study of a fragment of the radial color profile of the spiral galaxy M 31 in terms of 2-D model accounting for internal extinction in the disk. The two stellar population disk model was assumed.

Predictions and Outcomes for the Dynamics of Rotating Galaxies

open access: yesGalaxies, 2020
A review is given of a priori predictions made for the dynamics of rotating galaxies. One theory—MOND—has had many predictions corroborated by subsequent observations.

Galaxy formation [PDF]

open access: yesSymposium - International Astronomical Union, 1987
Theories of galaxy formation via hierarchical clustering of cold dark matter and by fragmentation of gaseous pancakes or shells are reviewed and compared. Dissipative processes are crucial to all theories of galaxy formation, and are discussed in terms of a simple model involving multiple cloud interactions.

Bar fraction in lenticular galaxies: dependence on luminosity and environment

open access: yes, 2010
We present a study of bars in lenticular galaxies based on a sample of 371 galaxies from the SDSS-DR 7 and 2MASS in optical and near-infrared bands, respectively.

Quantitative Morphology of Galaxies in the Hubble Deep Field [PDF]

open access: yes, 1998
We measure quantitative structural parameters of galaxies in the Hubble Deep Field (HDF) on the drizzled F814W images. Our structural parameters are based on a two-component surface brightness made up of a S\'ersic profile and an exponential profile.
