A Photometric Study of Giant Ellipticals and Their Stellar Halos With VST

Galaxies, 2017
Observations of diffuse starlight in the outskirts of galaxies are thought to be a fundamental source of constraints on the cosmological context of galaxy assembly in the Λ CDM model.

Hubble Space Telescope Imaging of the CFRS and LDSS Redshift Surveys---III. Field elliptical galaxies at 0.2 < z < 1.0

, 1999
Surface photometry has been performed on a sample of 46 field elliptical galaxies. These galaxies are described well by a deVaucouleurs R^{1/4} profile. The sample was selected from the combined Canada-France and LDSS redshift surveys and spans the range

A search for HI in five elliptical galaxies with fine structure [PDF]

, 2002
We report on VLA H I spectral line observations of five early-type galaxies classified as optically peculiar because of the presence of jets, ripples, or other optical fine structure.

High resolution soft x-ray spectroscopy of the elliptical galaxy NGC 5044. Results from the reflection grating spectrometer on-board XMM-Newton [PDF]

, 2002
The results from an X-ray spectroscopic study of the giant elliptical galaxy NGC 5044 in the center of a galaxy group are presented. The line dominated soft X-ray spectra (mainly Fe-L and $\ion{O}{viii}$ ${\rm Ly\alpha}$) from the diffuse gas are ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Simulations of Galaxy Formation in a ΛCDM Universe. III. The Dissipative Formation of an Elliptical Galaxy [PDF]

, 2003
We examine the dynamical structure of an elliptical galaxy simulated in the ΛCDM scenario. The morphology of the galaxy evolves dramatically over time in response to the mode and timing of mass accretion; smooth deposition of cooled gas leads to the ...

Proton‐linked effects on the axial coordination in ferric and ferrous horse heart cytochrome c

Protein Science, Volume 34, Issue 11, November 2025.
Abstract The effect of pH (between pH 7.0 and 0.0) on the spectroscopic properties of ferric and ferrous derivatives of horse heart cytochrome c (hhcytc‐Fe(III) and hhcytc‐Fe(II), respectively) in 1.0M phosphate buffer is reported. This study further deepens the investigation of spectroscopic properties of a heme‐protein to very low pH (i.e., pH ≈ 0 ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

Journal of Research in Science Teaching, Volume 62, Issue 8, Page 1902-1922, October 2025.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).
