Superwinds and the nature of starburst galaxies [PDF]
Symposium - International Astronomical Union, 1999 I discuss the observational evidence that starburst galaxies are able to drive galactic-scale outflows ('superwinds') and then argue generally that superwinds must have had an important role in galaxy evolution. To explore the role of feedback from massive stars, I review results suggesting that starbursts seem to obey a limiting IR surface brightness ...

Imaging FTS: A Different Approach to Integral Field Spectroscopy
Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014 Imaging Fourier transform spectroscopy (iFTS) is a promising, although technically very challenging, option for wide‐field hyperspectral imagery. We present in this paper an introduction to the iFTS concept and its advantages and drawbacks, as well as examples of data obtained with a prototype iFTS, SpIOMM, attached to the 1.6 m telescope of the ...

Chemodynamical Simulations of Dwarf Galaxy Evolution
Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014 In this review I give a summary of the state of the art for what concerns the chemo‐dynamical numerical modelling of galaxies in general and of dwarf galaxies in particular. In particular, I focus my attention on (i) initial conditions, (ii) the equations to solve; (iii) the star formation process in galaxies, (iv) the initial mass function, (v) the ...

Anomalous Microwave Emission from Star Forming Regions
Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013 The evidence for microwave emission from spinning dust grains has been strengthened considerably by its detection in a number of discrete astrophysical objects associated with star formation. These detections, in combination with statistical constraints on its presence on large angular scales in the diffuse ISM, have provided strong observational ...

Overtone Transition 2ν1 of HCO+ and HOC+: Origin, Radiative Lifetime, Collisional Quenching
ChemPhysChem, Volume 25, Issue 21, November 4, 2024.The C−H/O−H stretch vibration overtone of one of the simplest molecular ion isomeric systems HCO+/HOC+ is studied in a cryogenic ion trap experiment. Moreover, our comprehensive “zero background” method enables the determination of radiative lifetimes and select quenching reaction rates at the same time.

Properties of the Hii Regions Derived Using Integral Field Spectroscopy
Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013 Here we review some of our more recent results on the observed properties of Hii regions using Integral Field Spectroscopy. In particular, we illustrate the use of this technique to study in detail the ionization conditions across the nebulae for galactic Hii regions (focused on the Orion Nebula) and the statistical study of large samples of ...

The Evolutionary Sequence of Post-Starburst Galaxies [PDF]
, 2017 There are multiple ways in which to select post-starburst galaxies in the literature. In this work, we present a study into how two well-used selection techniques have consequences on observable post-starburst galaxy parameters, such as colour ...

Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics
Annalen der Physik, Volume 536, Issue 2, February 2024.Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

The Study of Nebular Emission on Nearby Spiral Galaxies in the IFU Era
Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013 A new generation of wide‐field emission‐line surveys based on integral field units (IFU) is allowing us to obtain spatially resolved information of the gas‐phase emission in nearby late‐type galaxies, based on large samples of HII regions and full two‐dimensional coverage.
