THE LOCAL DWARF GALAXIES:BUILDING BLOCKS OFMASSIVE ONES? I.THE FORNAX DWARF GALAXY

Odessa Astronomical Publications, 2008
A chemical evolution of the Local Group dwarf galaxy Fornax is considered in the framework of the merger scenario. We suppose a galactic stellar halo to be formed as separate fragments which then merge; thus, we can calculate the set of such the ...

Hickson 62.I. Kinematics of NGC4778 [PDF]

, 2006
Detailed studies of the photometric and kinematical properties of compact groups of galaxies are crucial to understand the physics of galaxy interactions and to shed light on some aspects of galaxy formation and evolution.

Galaxy And Mass Assembly: Estimating galaxy group masses via caustic analysis [PDF]

, 2012
We have generated complementary halo mass estimates for all groups in the Galaxy And Mass Assembly Galaxy Group Catalogue (GAMA G3Cv1) using a modified caustic mass estimation algorithm, originally developed by Diaferio & Geller (1997).

The Local Group on FIRE: dwarf galaxy populations across a suite of hydrodynamic simulations [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We present a new set of high-resolution hydrodynamic cosmological zoom-in simulations that apply the Feedback In Realistic Environments physics to both Local Group (LG)-like and isolated Milky Way (MW)-like volumes (10 host systems in total with a ...

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

Advanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

HerS-3: An Exceptional Einstein Cross Reveals a Massive Dark Matter Halo

The Astrophysical Journal
We present a study of HerS-3, a dusty star-forming galaxy at z _spec  = 3.0607, which is gravitationally amplified into an Einstein cross with a fifth image of the background galaxy seen at the center of the cross.

NGC1600 - Cluster or Field Elliptical?

, 2008
A study of the galaxy distribution in the field of the elliptical galaxy NGC1600 has been undertaken. Although this galaxy is often classified as a member of a loose group, all the neighbouring galaxies are much fainter and could be taken as satellites ...
