Dynamics of Galaxy Interactions [PDF]

open access: yes, 1998
This review briefly and very informally summarizes some of my ongoing research. One unifying theme in my work is the use of computers to bridge the gap between human and astronomical time-scales. Galactic collisions are an example; the dynamics of interacting galaxies can be visualized with numerical simulations.

Photopatternable PEDOT:PSS Hydrogels for High‐Resolution Photolithography

open access: yesAdvanced Science, EarlyView.
A photosensitive biphasic conducting polymer hydrogel (PB‐CH) is rationally designed with PEDOT:PSS as the conductive phase and a light‐sensitive matrix as the mechanical phase. Such a PB‐CH offers a unique combination of excellent conductivity (≈30 S cm⁻¹), robust mechanical performance (with stretchability up to 50%), and high photopatternability ...

The Small-Scale Structure of the Magellanic Stream as a Foundation for Galaxy Evolution [PDF]

open access: yesSerbian Astronomical Journal, 2010
The Magellanic Stream (MS) is the nearest example of agaseous trail formed by interacting galaxies. While the substantial gas masses in these kinds of circumgalactic structures are postulated to represent important sources of fuel for future star ...

Discovery of a Rare Group of Dwarf Galaxies in the Local Universe

open access: yesThe Astrophysical Journal Letters
We report the discovery of a rare isolated group of five dwarf galaxies located at z = 0.0086 ( D = 36 Mpc). All member galaxies are star forming, blue, and gas rich, with g − r indices ranging from 0.2 to 0.6 mag, and two of them show signs of ongoing ...

Major Mergers as Possible Drivers of the Galaxy Mass Assembly in the Early Universe: New Insights from ALMA Observations

open access: yesPhysical Sciences Forum, 2023
Galaxies are thought to grow through star formation or by interacting with each other. To understand which process dominates, we investigated the contribution of major mergers to the galaxy mass assembly across cosmic time.

Disturbed isolated galaxies: indicators of a dark galaxy population? [PDF]

open access: yes, 2006
We report the results of our search for disturbed (interacting) objects among very isolated galaxies. The inspections of 1050 northern isolated galaxies from KIG and 500 nearby, very isolated galaxies situated in the Local Supercluster yielded five and four strongly disturbed galaxies, respectively.

Measuring dark matter by modeling interacting galaxies

open access: yes, 2009
The dark matter content of galaxies is usually determined from galaxies in dynamical equilibrium, mainly from rotationally supported galactic components. Such determinations restrict measurements to special regions in galaxies, e.g. the galactic plane(s),

The Nature of LoBAL QSOs. II. HST/WFC3 Observations Reveal Host Galaxies Dominated by Mergers

open access: yesThe Astrophysical Journal, 2023
Low-ionization broad absorption line QSOs (LoBALs) are suspected to be merging systems in which extreme, active galactic nucleus-driven outflows have been triggered.

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.
