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 ...

LATE-STAGE GALAXY MERGERS IN COSMOS TO z ∼ 1 [PDF]
, 2014 The role of major mergers in galaxy and black hole formation is not well-constrained. To help address this, we develop an automated method to identify late-stage galaxy mergers before coalescence of the galactic cores.

KYDISC: Galaxy Morphology, Quenching, and Mergers in the Cluster Environment [PDF]
Astrophysical Journal Supplement Series, 2018 We present the KASI-Yonsei Deep Imaging Survey of Clusters targeting 14 clusters at 0.015 ≲ z ≲ 0.144 using the Inamori Magellan Areal Camera and Spectrograph on the 6.5 m Magellan Baade telescope and the MegaCam on the 3.6 m Canada–France–Hawaii ...

THE MERGER-DRIVEN EVOLUTION OF MASSIVE GALAXIES [PDF]
The Astrophysical Journal, 2010 We explore the rate and impact of galaxy mergers on the massive galaxy population using the amplitude of the two-point correlation function on small scales for M > 5e10 M_sun galaxies from the COSMOS and COMBO-17 surveys. Using a pair fraction derived from the Sloan Digital Sky Survey as a low-redshift benchmark, the large survey area at ...

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 ...

Event Rate of Fast Radio Bursts from Binary Neutron Star Mergers
The Astrophysical Journal, 2023 It is proposed that a one-off fast radio burst (FRB) with periodic structure may be produced during the inspiral phase of a binary neutron star (BNS) merger. In this paper, we study the event rate of such kind of FRB.

DIRECT FORMATION OF SUPERMASSIVE BLACK HOLES IN METAL-ENRICHED GAS AT THE HEART OF HIGH-REDSHIFT GALAXY MERGERS [PDF]
, 2014 We present novel 3D multi-scale smoothed particle hydrodynamics (SPH) simulations of gas-rich galaxy mergers between the most massive galaxies at z ∼ 8–10, designed to scrutinize the direct collapse formation scenario for massive black hole seeds ...
