The temporal changes in the emission spectrum of Comet 9P/Tempel 1 after Deep Impact [PDF]
, 2009 The time dependence of the changes in the emission spectra of Comet 9P/Tempel 1 after Deep Impact are derived and discussed. This was a unique event because for the first time it gave astronomers the opportunity to follow the time history of the ...

The Photodissociation and Ionization Fronts in M17-SW Localized with FIFI-LS on Board SOFIA
The Astrophysical Journal, 2023 To understand star formation rates, studying feedback mechanisms that regulate star formation is necessary. The radiation emitted by nascent massive stars play a significant role in feedback by photodissociating and ionizing their parental molecular ...

Jitter-correction for IR/UV-XUV pump-probe experiments at the FLASH free-electron laser
New Journal of Physics, 2017 In pump-probe experiments employing a free-electron laser (FEL) in combination with a synchronized optical femtosecond laser, the arrival-time jitter between the FEL pulse and the optical laser pulse often severely limits the temporal resolution that can

Ultrafast F2− photodissociation by intense laser pulses: a time-resolved fragment imaging study [PDF]
EPJ Web of Conferences, 2019 We present time-resolved coincidence imaging of F2− photodissociation by 400nm and intense 800nm ultrafast pulses. Coincidence fragment imaging reveals parallel and perpendicular single photon dissociation on 2Σg+ and 2πg states, and additional intense ...

Radiative feedback from ionized gas [PDF]
Mon.Not.Roy.Astron.Soc.379:1352-1358,2007, 2007 H2 formation in metal-free gas occurs via the intermediate H- or H2+ ions. Destruction of these ions by photodissociation therefore serves to suppress H2 formation. In this paper, I highlight the fact that several processes that occur in ionized primordial gas produce photons energetic enough to photodissociate H- or H2+ and outline how to compute the ...
