The baryon cycle in galaxy mergers

, 2017
Galaxy mergers are well known to dramatically alter not only morphology and structure, but also the internal constituents of galaxies. In this talk I will focus on the baryon cycle within galaxy mergers, whereby gas is converted to stars, which ...

Signatures of Massive Black Hole Merger Host Galaxies from Cosmological Simulations. I. Unique Galaxy Morphologies in Imaging

The Astrophysical Journal
Low-frequency gravitational-wave experiments such as the Laser Interferometer Space Antenna and pulsar timing arrays are expected to detect individual massive black hole (MBH) binaries and mergers.

Quasars Can Signpost Supermassive Black Hole Binaries

The Astrophysical Journal
Supermassive black holes (SMBHs) are found in the centers of massive galaxies, and galaxy mergers should eventually lead to SMBH mergers. Quasar activity has long been associated with galaxy mergers, so here we investigate if supermassive black hole ...

Molecular Gas and Star Formation in Nearby Starburst Galaxy Mergers

The Astrophysical Journal, 2023
We employ the Feedback In Realistic Environments (FIRE-2) physics model to study how the properties of giant molecular clouds (GMCs) evolve during galaxy mergers.

Observing Galaxy Mergers at the Epoch of Reionization

The Astrophysical Journal, 2018
Abstract The galaxies with photometric redshifts observed in a close angular proximity might be either projection coincidences, strongly lensed images of the same galaxy, or separate galaxies that are in a stage of merging. We search for the groups of galaxies in the Hubble Ultra Deep Field (HUDF09) in z ∼ 7 and z ∼ 8 drop-out samples ...

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

Journal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.

Massive Black Hole Binaries: Dynamical Evolution and Observational Signatures

Advances in Astronomy, 2012
The study of the dynamical evolution of massive black hole pairs in mergers is crucial in the context of a hierarchical galaxy formation scenario. The timescales for the formation and the coalescence of black hole binaries are still poorly constrained ...

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.

On the Use of Galaxy Catalogs in Gravitational-wave Parameter Estimation

The Astrophysical Journal
A major challenge in gravitational-wave (GW) multimessenger astrophysics is the imprecise localization of GW compact binary mergers. We investigate the use of a method to include galaxy catalog information in performing parameter estimation of these ...

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.
