Chimneys in the starburst galaxy M 82 [PDF]
Symposium - International Astronomical Union, 1999 A new radio image of the core of the starburst galaxy M82 is presented. A pair of probable galactic chimneys are evident. Such structures have been conjectured to result when a giant shell of ionized gas breaks out of the dense plane of a galaxy and ejects hot gas into the halo.

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 ...

Post-starburst galaxies in SDSS-IV MaNGA [PDF]
, 2019 Funding: European Research Council via the award of a starting grant (SEDMorph; P.I. V. Wild) (VW, KR).Post-starburst galaxies, identified by their unusually strong Balmer absorption lines and weaker than average emission lines, have traditionally been ...

An Explanation for the Overrepresentation of Tidal Disruption Events in Post-starburst Galaxies
The Astrophysical Journal, 2023 Tidal disruption events (TDEs) provide a valuable probe for studying the dynamics of stars in the nuclear environments of galaxies. Recent observations show that TDEs are strongly overrepresented in post-starburst or “green valley” galaxies, although 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 ...

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.
