Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]

, 2006
In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

Galaxy Mergers Moulding the CGM

, 2017
Galaxies are surrounded by sizeable gas reservoirs which host a significant amount of metals: the circum-galactic medium (CGM). The CGM acts as a mediator between the galaxy and the extra-galactic medium. However, our understanding of how galaxy mergers,

Apparent Effect of Dust Extinction on the Observed Outflow Velocity of Ionized Gas in Galaxy Mergers

The Astrophysical Journal
In this study, we examine photoionization outflows during the late stages of galaxy mergers, with a specific focus on the relation between the observed velocity of outflowing gas and the apparent effects of dust extinction.

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Eight Gigayears of Galaxy Mergers

, 2010
Galaxy interactions are expected to play a crucial role in the build--up of stellar mass in any cold dark matter cosmology. Of particular interest are the mergers between systems of a comparable mass, as they are predicted to be one of the main modes of ...

Enhanced Star Formation and Black Hole Accretion Rates in Galaxy Mergers in IllustrisTNG50

The Astrophysical Journal
Many theoretical and observational studies have suggested that galaxy mergers may trigger enhanced star formation or active galactic nucleus 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.

Secondary evolution of galaxies investigated by N-body simulations

, 2008
In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

CLEC14A correlates with neutrophil infiltration in hepatocellular carcinoma and mediates neutrophil recruitment across liver endothelial cells

The Journal of Pathology, EarlyView.
Abstract Hepatocellular carcinoma (HCC) is a leading cause of cancer‐related deaths globally, and cases are predicted to rise dramatically over the next few years. Overcoming the immune microenvironment in HCC remains a challenge, and innate immune populations such as tumour‐associated neutrophils can potentially impair the success of immunotherapy ...

Intermediate Mass Ratio Inspirals in Milky Way Galaxies

The Astrophysical Journal
A consequence of a nonzero occupation fraction of massive black holes (MBHs) in dwarf galaxies is that these MBHs can become residents of larger galaxy halos via hierarchical merging and tidal stripping.
