X-ray properties of early-type galaxies [PDF]
, 2002 It has been known for some time that many early–type galaxies possess halos of X–ray emitting gas. However, the properties of these halos and the processes by which they form are as yet not well understood. We have compiled the largest catalogue of X–ray

Galaxy Dynamics from Edge-On Late-type Galaxies
, 1999 We present first results of a program to study the dynamics of undisturbed bulgeless, low surface density disk galaxies in order to probe the underlying structure of dark matter halos. High resolution H-alpha rotation curves are combined with optical and infrared imaging to place strong limits on the halo profiles.

Stellar halo constraints on simulated late-type galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 How do late-type spiral galaxies form within the context of a cold dark matter cosmology? We contrast N-body, smoothed particle hydrodynamical simulations of galaxy formation that employ two different supernova feedback mechanisms. Observed mass and metallicity distributions of the stellar haloes of the Milky Way and M31 provide constraints on these ...

Understanding the Fundamental Plane and the Tully Fisher Relation
Frontiers in Astronomy and Space Sciences, 2020 The relation between early type galaxy size, surface brightness and velocity dispersion, “the fundamental plane,” has long been understood as resulting from equilibrium in their largely pressure supported stellar dynamics.

Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions
Advanced Materials, EarlyView.This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

Continuum Robots in Surgery: From Engineering Design to Clinical Practice
Advanced Robotics Research, EarlyView.The hyper‐redundant nature of continuum robot structures enables near‐infinite degrees of freedom leading to immense potential for medical applications. This review provides a historical background of continuum robots and novel ideas shaping their progress to current structural design, sensing technology, modeling techniques, and control methods.
