Optical Observations of M81 Galaxy Group in Narrow Band [SII] and H_alpha Filters: Holmberg IX [PDF]

Serbian Astronomical Journal, 2009
We present observations of the nearby tidal dwarf galaxy Holmberg IX in M81 galaxy group in narrow band [SII] and H$alpha$ filters, carried out in March and November 2008 with the 2m RCC telescope at NAO Rozhen, Bulgaria.

Systematically Measuring Ultradiffuse Galaxies (SMUDGes). IV. Ultradiffuse Satellites of Milky Way Analogs

The Astronomical Journal, 2023
To better understand the formation of large, low-surface-brightness galaxies, we measure the correlation function between ultradiffuse galaxy (UDG) candidates and Milky Way analogs (MWAs).

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 (GAMA): the GAMA galaxy group catalogue (G3Cv1) [PDF]

, 2011
Using the complete Galaxy and Mass Assembly I (GAMA-I) survey covering ∼142 deg2 to rAB= 19.4, of which ∼47 deg2 is to rAB= 19.8, we create the GAMA-I galaxy group catalogue (G3Cv1), generated using a friends-of-friends (FoF) based grouping algorithm ...

Galaxy Assembly Bias in the Stellar-to-halo Mass Relation for Red Central Galaxies from SDSS

The Astrophysical Journal
We report evidence of galaxy assembly bias—the correlation between galaxy properties and biased secondary halo properties at fixed halo mass ( M _H )—in the stellar-to-halo mass relation for red central galaxies from the Sloan Digital Sky Survey.

The Leo-I group: new dwarf galaxy and ultra diffuse galaxy candidates [PDF]

Astronomy & Astrophysics, 2018
Context. The study of dwarf galaxies and their environments provides crucial test beds for predictions of cosmological models and insights into the structure formation on small cosmological scales. In recent years, many problems on the scale of groups of

Chandra Observations of the Interacting NGC 4410 Galaxy Group

, 2003
We present high resolution X-ray imaging data from the ACIS-S instrument on the Chandra telescope of the nearby interacting galaxy group NGC 4410. Four galaxies in the inner portion of this group are clearly detected by Chandra, including the peculiar ...

DEEP CHANDRA OBSERVATIONS OF EDGES AND BUBBLES IN THE NGC 5846 GALAXY GROUP [PDF]

, 2011
We use a combined 120 ks Chandra exposure to analyze X-ray edges produced by non-hydrostatic gas motions (sloshing) from galaxy collisions, and cavities formed by active galactic nucleus (AGN) activity.

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

People 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.
