The clustering of galaxies in hierarchical galaxy formation models [PDF]
, 2010 Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

How ventures maintain stakeholder support amidst operational legitimacy threats
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary We explore how ventures mitigate operational legitimacy threats—threats that originate within the venture and challenge claims relating to the venture's ability to deliver on its promised value proposition. Through an inductive study of four ventures working to deliver their promised products following successful crowdfunding ...

COMPLETE ELEMENT ABUNDANCES OF NINE STARS IN THE r-PROCESS GALAXY RETICULUM II [PDF]
, 2016 We present chemical abundances derived from high-resolution Magellan/Magellan Inamori Kyocera Echelle spectra of the nine brightest known red giant members of the ultra-faint dwarf galaxy Reticulum II (Ret II). These stars span the full metallicity range

The Hubble Constant Anchor Galaxy NGC 4258: Metallicity and Distance from Blue Supergiants
The Astrophysical JournalA quantitative spectroscopic study of blue supergiant stars in the Hubble constant anchor galaxy NGC 4258 is presented. The non-LTE analysis of Keck I telescope LRIS spectra yields a central logarithmic metallicity (in units of the solar value) of [ Z ] =

The Momentum of ‘Developed’: Bodies of Water, Aging Bodies and Malta's Interventions at the UN
History, EarlyView.Abstract Histories of major powers continue to shape how many scholars conceptualize internationalism. By focusing on Malta's interventions at the UN challenges, this article challenges such narrative. In particular, it examines Arvid Pardo's 1967 petition that the seabed be reconceived and protected as the ‘common heritage of mankind’ and Vincent ...

Effects of Multiple Spiral Arm Patterns on the Abundance Gradients of Heavy Elements
GalaxiesUnderstanding how spiral structures influence the chemical evolution of the Galactic disc remains a key issue in Galactic archaeology. Recent advances in two-dimensional chemical evolution modeling allow us to account for the impact of multiple spiral ...

The Chemodynamics of the Stellar Populations in M31 from APOGEE Integrated-light Spectroscopy
The Astrophysical Journal, 2023 We present an analysis of nearly 1000 near-infrared, integrated-light spectra from APOGEE in the inner ∼7 kpc of M31. We utilize full-spectrum fitting with A-LIST simple stellar population spectral templates that represent a population of stars with the ...

SFR and Abundances of Nearby Galaxies [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractWe present star formation rates and nebular abundances of 59 different star-forming regions in 16 nearby galaxies. The star-forming regions were selected to be bright in Hα and were observed with the SNIFS integral field spectrograph on the UH 2.2m telescope. The spectra span the wavelength range between 3200Å and 1μm.

International Journal of Urban and Regional Research, EarlyView.Abstract In terms of mainstream sustainability economics, market‐led initiatives aimed at biodiversity restoration represent a productive, morally conscientious choice. Under this view, efforts in areas such as biodiversity offsetting, net gain, or finance are considered effective tools for preventing or managing environmental degradation.

Exploring the Gas-phase Metallicity Gradients of Star-forming Galaxies at Cosmic Noon
The Astrophysical JournalWe explore the relationships between the [O/H] gas-phase metallicity radial gradients and multiple galaxy properties for 238 star-forming galaxies at 0.6 < z < 2.6 selected from the CANDELS Ly α Emission at Reionization survey with stellar mass $8.5\lt ...
