PHOTOMETRIC DECOMPOSITION OF MERGERS IN DISK GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2014
Several observational studies and numerical simulations suggest that mergers must contribute to the evolution of galaxies; however, the role that they play is not yet fully understood. In this paper we study a sample of 52 double nucleus disk galaxies that are considered as candidates for a minor merger event.

Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions

open access: yesAdvanced Intelligent Systems, EarlyView.
Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

On the Progenitor of Binary Neutron Star Merger GW170817

open access: yesThe Astrophysical Journal Letters, 2017
On 2017 August 17 the merger of two compact objects with masses consistent with two neutron stars was discovered through gravitational-wave (GW170817), gamma-ray (GRB 170817A), and optical (SSS17a/AT 2017gfo) observations.

Massive Black Hole Binaries from the TNG50-3 Simulation. II. Using Dual AGNs to Predict the Rate of Black Hole Mergers

open access: yesThe Astrophysical Journal, 2023
Dual active galaxy nuclei (dAGNs) trace the population of post-merger galaxies and are the precursors to massive black hole (MBH) mergers, an important source of gravitational waves that may be observed by the Laser Interferometer Space Antenna (LISA ...

Galaxy pairs in the Sloan Digital Sky Survey – IX. Merger-induced AGN activity as traced by the Wide-field Infrared Survey Explorer [PDF]

open access: yes, 2014
Interactions between galaxies are predicted to cause gas inflows that can potentially trigger nuclear activity. Since the inflowing material can obscu re the central regions of interacting galaxies, a potential limitation of previous optical st udies is ...

Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

open access: yesAdvanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

A comparison of galaxy merger history observations and predictions from semi-analytic models [PDF]

open access: yes, 2009
Mergers are predicted in all cosmological models involving cold dark matter (CDM) to be one of the dominant channels whereby galaxies accrete mass. In this paper, we present a detailed analysis of predicted galaxy-galaxy merger fractions and rates in the

Observable signatures of a black hole ejected by gravitational-radiation recoil in a galaxy merger. [PDF]

open access: yesPhysical Review Letters, 2007
According to recent simulations, the coalescence of two spinning black holes (BHs) could lead to a BH remnant with recoil speeds of up to thousands of km s(-1).

Sersic properties of disc galaxy mergers [PDF]

open access: yesMonthly 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.

Parametric Design of Continuum Robots Using Interlocking Ball Joints

open access: yesAdvanced Intelligent Systems, EarlyView.
Herein, a parametric design methodology is introduced for producing a wide variety of modular ball joint‐based continuum robots. It is demonstrate by designing a magnetically actuated continuum robot for cardiac ablations. The methodology is released as an open‐source computer‐assisted design extension that automatically designs continuum robots based ...
