Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies
Frontiers in Astronomy and Space Sciences, 2022 We discuss the role of planetary nebulae and their progeny in galaxy context in terms of ionization of the galaxy interstellar medium. This regards ionized gas outside the disk of spiral galaxies, the diffuse ionized medium in spiral galaxies, and the ...

Ionization-Gasdynamic Simulations of Wind-Blown Nebulae around Massive Stars
Galaxies, 2022 Using a code that employs a self-consistent method for computing the effects of photo-ionization on circumstellar gas dynamics, we model the formation of wind-driven nebulae around massive stars.

Cavity-enhanced photoionization of an ultracold rubidium beam for application in focused ion beams [PDF]
, 2017 A two-step photoionization strategy of an ultracold rubidium beam for application in a focused ion beam instrument is analyzed and implemented. In this strategy the atomic beam is partly selected with an aperture after which the transmitted atoms are ...

The different origins of high- and low-ionization broad emission lines revealed by gravitational microlensing in the Einstein cross [PDF]
, 2016 We investigate the kinematics and ionization structure of the broad emission line region of the gravitationally lensed quasar QSO2237+0305 (the Einstein cross) using differential microlensing in the high- and low-ionization broad emission lines.

The physical chemistry of the enigmatic phospholipid diacylglycerolpyrophosphate
Frontiers in Plant Science, 2012 Phosphatidic acid (PA) is a lipid second messenger that is formed transiently in plants in response to different stress conditions, and plays a role in recruiting protein targets, ultimately enabling an adequate response.
