Observed Evidence for the Primordial Origin of Galaxy Sizes

open access: yesThe Astrophysical Journal
We present observational evidence supporting the scenario that the protogalactic angular momenta play an important role in molding the optical sizes of present galaxies. Analyzing the NASA-Sloan Atlas catalog in the redshift range of 0.02 ≤ z

Low luminosity elliptical galaxies [PDF]

open access: yes, 1998
Long-slit spectra for the photometric axes of a sample of 14 elliptical galaxies, predominantly low-luminosity ellipticals, in the Virgo cluster and in nearby groups, are studied to investigate the galaxy kinematical structure and stellar evolutionary ...

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

open access: yesPeople and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

Molecular gas in late-type galaxies

open access: yes, 2001
We present $^{12}$CO(J=1--0) line observations of 22 low-luminosity spiral galaxies in the Virgo cluster. These data, together with 244 others available in the literature, allow us to build a large sample that we use to study the molecular gas properties of galaxies spanning a large range of morphological types and luminosities and belonging to ...

Simulating molecular cloud regulated star formation in Galaxies [PDF]

open access: yes, 2007
This thesis is primarily concerned with understanding the process of galaxy formation via the simulation of the interstellar medium, star formation and supernova feedback.

The ATLAS(3D) project - XXV. Two-dimensional kinematic analysis of simulated galaxies and the cosmological origin of fast and slow rotators [PDF]

open access: yes, 2014
We present a detailed two-dimensional stellar dynamical analysis of as ample of 44 cosmological hydrodynamical simulations of individual central galaxies with stellar masses of 2 x 1010Msun ∼≤ Mstar ∼≤ 6x 1011Msun.

From Cluster Core to Splashback: Linking Dynamical Structure to Multidimensional Galaxy Evolution in the Coma Cluster

open access: yesThe Astrophysical Journal
We investigate galaxy evolution across the full dynamical structure of the Coma cluster using the GalWCat19 spectroscopic cluster catalog combined with Sloan Digital Sky Survey (SDSS) based value-added galaxy properties. We measure a splashback radius of

New morpho-kinematic classification: The two-dimensional spatial distribution of stellar specific angular momentum in late-type galaxies

open access: yesAstronomy & Astrophysics
Aims. The two-dimensional spatial distribution of stellar specific angular momentum (sAM) within galaxies has never been analysed. We seek to identify the morpho-kinematics of this property and its correlation with the total stellar sAM (j★) and the ...

The Crystal Structures of High‐ and Low‐Temperature Silver Pyrophosphate: Structural Instability and Its Consequences

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The crystal structures of the high‐temperature and low‐temperature phases of silver pyrophosphate are reported. The structural results are complemented by thermal analysis, vibrational and 31P‐MAS‐NMR spectroscopy studies, and density functional theory calculations.

Resolved Stellar Mass Estimation of Nearby Late-type Galaxies for the SPHEREx Era: Dependence on Stellar Population Synthesis Models

open access: yesThe Astronomical Journal
The upcoming all-sky infrared spectrophotometric SPHEREx mission is set to provide spatially resolved stellar mass maps of nearby galaxies, offering more detailed insights than integrated light observations.
