MAGICS I. The First Few Orbits Encode the Fate of Seed Massive Black Hole Pairs
The Open Journal of AstrophysicsThe elusive massive black hole (MBH) seeds stand to be revealed by the Laser Space Antenna Interferometer through mergers. As an aftermath of galaxy mergers, MBH coalescence is a vastly multi-scale process connected to galaxy formation. We introduce the "

Intermediate Mass Ratio Inspirals in Milky Way Galaxies
The Astrophysical JournalA 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.

Massive close pairs measure rapid galaxy assembly in mergers at high redshift [PDF]
, 2016 We compare mass-selected close pairs at z > 1 with the intrinsic galaxy merger rate in the Illustris Simulations. To do so, we construct three 140 arcmin^2 lightcone catalogs and measure pair fractions, finding that they change little or decrease with ...

Quantifying Imperfect Cognition Via Achieved Information Gain
Annalen der Physik, EarlyView.Cognition, the processing of information in the form of inference, communication, and memorization, is the central activity of any intelligence. To quantify imperfect cognition, the concept of achieved information gain (AIG) is introduced. AIG can be derived axiomatically, allows cognitive fidelity and efficiency to be defined mathematically, and ...

Outlier Detection in the DESI Bright Galaxy Survey
The Astrophysical Journal Letters, 2023 We present an unsupervised search for outliers in the Bright Galaxy Survey (BGS) data set from the DESI Early Data Release. This analysis utilizes an autoencoder to compress galaxy spectra into a compact, redshift-invariant latent space, and a ...

, 2019 The question of whether galaxy mergers are linked to the triggering of active galactic nuclei (AGN) continues to be a topic of considerable debate. The issue can be broken down into two distinct questions: 1) Can galaxy mergers trigger AGN? 2) Are galaxy

Sersic properties of disc galaxy mergers [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 Sersic parameters characterising the density profiles of remnants formed in collision-less disc galaxy mergers are obtained; no bulge is included in our simulations. For the luminous component we find that the Sersic index is n ~ (1.5,5.3) with ~ 3 +/- 1 and an effective radius of R_e ~ (1.6,12.9) kpc with ~ 5 +/- 3 kpc.

Schrödinger's Doctrine of Identity: On the Role of Advaita Vedānta in Erwin Schrödinger's Thought
Berichte zur Wissenschaftsgeschichte, EarlyView.Ever since Erwin Schrödinger learned about Indian thought through Arthur Schopenhauer, it occupied a visible role in both his published writings and personal books. Schrödinger called for a “blood transfusion” of Indian thought into the West and, in one notebook, construed the Upaniṣadic slogan “Brahman = Atman” as the “closest thing to the truth ...

Kinematic classifications of local interacting galaxies: implications for the merger/disk classifications at high-z [PDF]
, 2015 The classification of galaxy mergers and isolated disks is key for understanding the relative importance of galaxy interactions and secular evolution during the assembly of galaxies.

DYNAMICAL MODELING OF GALAXY MERGERS USING IDENTIKIT [PDF]
, 2013 We present dynamical models of four interacting systems: NGC 5257/8, The Mice, the Antennae, and NGC 2623. The parameter space of the encounters are constrained using the Identikit model-matching and visualization tool.
