Ghost in the Shell: Evidence for Past Active Galactic Nucleus Activities in NGC 5195 from a Newly Discovered Large-scale Ionized Structure

The Astrophysical Journal, 2023
The early-type galaxy NGC 5195 (alternatively known as M51b) possesses extended gas features detected in the multiwavelength, postulated to be associated with previous activities of the central supermassive black hole.

Dynamics of Galaxy Interactions [PDF]

, 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.

Radiation Hardened Infrared Photodetectors Based on a Narrow Bandgap Conjugated Polymer Semiconductor

Advanced Electronic Materials, EarlyView.
A blackbody‐sensitive infrared photodetector comprised of an open‐shell conjugated polymer demonstrates high sensitivity without cooling and exceptional radiation hardness, surpassing inorganic compound semiconductor devices. This functionality, inherent to the polymer semiconductor, provides a new frontier for low‐cost, size, weight, and power space ...

Super-star clusters versus OB associations

, 2010
Super Star Clusters (Mecl > 10^5 Msol) are the largest stellar nurseries in our local Universe, containing hundreds of thousands to millions of young stars within a few light years.

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

Advanced 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.

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

Serbian 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

The 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 ...

Effect of the Environment on the Fundamental Plane of Elliptical Galaxies [PDF]

, 2000
We present an analysis of interacting E/S0 galaxies location on the Fundamental Plane. Using the NEMO package, we performed N-body simulations of close encounters and mergers between two spherical galaxies.

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

Advanced 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 ...

Gas-Phase Oxygen Gradients in Strongly Interacting Galaxies: I. Early-Stage Interactions

, 2010
A consensus is emerging that interacting galaxies show depressed nuclear gas metallicities compared to isolated star-forming galaxies. Simulations suggest that this nuclear underabundance is caused by interaction-induced inflow of metal-poor gas, and ...
