APEX CO observations towards the photodissociation region of RCW 120
(EDP Science, 2020)
Context. The edges of ionized (HII) regions are important sites for the formation of (high-mass) stars. Indeed, at least 30% of the Galactic high-mass-star formation is observed there. The radiative and compressive impact ...
Large scale map of millimeter wavelength hydrogen radio recombination lines around a young massive star cluster
(IOP Publishing Ltd, 2017)
We report the first map of large-scale (10 pc in length) emission of millimeter-wavelength hydrogen recombination lines (mm-RRLs) toward the giant H II region around the W43-Main young massive star cluster (YMC). Our mm-RRL ...
Rotation in [C II]-emitting gas in two galaxies at a redshift of 6.8
(Nature Publishing Group, 2018)
The earliest galaxies are thought to have emerged during the first billion years of cosmic history, initiating the ionization of the neutral hydrogen that pervaded the Universe at this time. Studying this 'epoch of ...
A Spitzer Space Telescope survey of massive young stellar objects in the G333.2-0.4 giant molecular cloud
The G333 giant molecular cloud contains a few star clusters and Hii regions, plus a number of condensations currently forming stars. We have mapped 13 of these sources with the appearance of young stellar objects (YSOs) ...
Rapid-response mode VLT/UVES spectroscopy of GRB060418 - Conclusive evidence for UV pumping from the time evolution of FeII and NiII excited- and metastable-level populations
We present high-resolution spectroscopic observations of GRB 060418, obtained with VLT/UVES. These observations were triggered using the VLT Rapid-Response Mode (RRM), which allows for automated observations of transient ...
Space telescope and optical reverberation mapping project. iv. anomalous behavior of the broad ultraviolet emission lines in ngc 5548
(IOP Publishing, 2016)
During an intensive Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) UV monitoring campaign of the Seyfert 1 galaxy NGC 5548 performed from 2014 February to July, the normally highly correlated far UV continuum ...
