The Astrophysical JournalTo facilitate new studies of galaxy-merger-driven fueling of active galactic nuclei (AGNs), we present a catalog of 387 AGNs that we have identified in the final population of over 10,000 z < 0.15 galaxies observed by the Sloan Digital Sky Survey-IV ...

Simulations of Galaxy Mergers [PDF]
Symposium - International Astronomical Union, 1983 The last few years have seen a considerable amount of effort devoted to the problem of simulating the coalescence of galaxies. After a discussion of the merits and limitations of the N-body techniques that have been used, I summarise the insight this research gives into the mechanisms driving strong interactions in galaxy collisions and into the ...

HI observations of luminous infrared galaxy mergers [PDF]
, 2000 A total of 19 luminous infrared galaxy mergers, with L_(IR) ≳ 210^(11) L_⊙, for H_0 = 75 km s^(-1) Mpc^(-1), have been observed in the H i line at Nançay and four of them were observed at Arecibo as well.

Advanced Robotics Research, EarlyView.WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

Identifying Mergers in the Legacy Surveys with Few-shot Learning
The Astrophysical Journal Supplement SeriesGalaxy mergers exert a pivotal influence on the evolutionary trajectory of galaxies and the expansive development of cosmic structures. The primary challenge encountered in machine learning–based identification of merging galaxies arises from the ...

Formation of Globular Clusters in Galaxy Mergers [PDF]
Highlights of Astronomy, 2005 AbstractOur numerical simulations first demonstrate that the pressure of ISM in a major merger becomes so high (> 105 kB K cm-3) that GMCs in the merger can collapse to form globular clusters (GCs) within a few Myr. The star formation efficiency within a GMC in galaxy mergers can rise up from a few percent to ~ 80 percent, depending on the shapes ...

Growing the first galaxies’ merger trees
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Modelling the growth histories of specific galaxies often involves generating the entire population of objects that arise in a given cosmology and selecting systems with appropriate properties. This approach is highly inefficient when targeting rare systems such as the extremely luminous high-redshift galaxy candidates detected ...

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 ...
