Integral-Field Spectroscopy of High-Redshift Galaxies: Implications for Early Galaxy Evolution [PDF]

, 2006
Several lines of evidence suggest that the most active phase of galaxy evolution, especially in the most massive systems, was largely completed by $z\sim 1$.

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

Zeitschrift 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.

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Radial Gradients and Intrinsic Scatter in MaNGA Galaxies

The Astrophysical Journal Supplement Series
We derive stellar population parameters and radial gradients within 0.65 R _e for spatially resolved spectra of 2968 early-type galaxies from MaNGA, spanning stellar velocity dispersions ( σ ) of 50–340 km s ^−1 .

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

Journal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

MHD numerical simulations in a cosmological context [PDF]

, 2011
Magnetic fields in the Universe are found in almost all studied environments. In particular, their presence in the inter-galactic medium and in the intra-cluster medium is confirmed by diffuse radio emission as well as by observations of Faraday ...

Inside-out versus Upside-down: The Origin and Evolution of Metallicity Radial Gradients in FIRE Simulations of Milky Way-mass Galaxies and the Essential Role of Gas Mixing

The Astrophysical Journal
Within the Milky Way (MW), younger stellar populations exhibit steeper (more negative) metallicity radial gradients; the origin of this trend remains debated. The FIRE-2 cosmological simulations of MW-mass galaxies show the same trend as the MW, which in

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

Integrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Exploring the Relationship between Stellar Mass, Metallicity, and Star Formation Rate at z ∼ 2.3 in KBSS-MOSFIRE

The Astrophysical Journal
The metal enrichment of a galaxy is determined by the cycle of baryons in outflows, inflows, and star formation. The relative contribution and timescale of each process sets the relationship between stellar mass, metallicity, and the star formation rate (
