Multi-scale stamps for real-time classification of alert streams
Ignacio Reyes-Jainaga, Francisco Förster, Alejandra M. Muñoz Arancibia +15
In recent years, automatic classifiers of image cutouts (also called "stamps") have shown to be key for fast supernova discovery. The Vera C. Rubin Observatory will distribute abou…
Structural investigation of doubly-dehydrogenated pyrene cations
Sanjana Panchagnula, Jordy Bouwman, Daniël B. Rap +7
The vibrationally resolved spectra of the pyrene cation and doubly-dehydrogenated pyrene cation (CH; Py and CH; ddPy) are presented…
Laboratory gas-phase infrared spectra of two astronomically relevant PAH cations: diindenoperylene, CH and dicoronylene, CH
Junfeng Zhen, Alessandra Candian, Pablo Castellanos +3
The first gas-phase infrared spectra of two isolated astronomically relevant and large PAH cations - diindenoperylene (DIP) and dicoronylene (DC) - in the 5301800 cm (18.…
Infrared Spectra of Hexa-peri-hexabenzocoronene Cations:HBC+ and HBC2+
Junfeng Zhen, Pablo Castellanos, Jordy Bouwman +2
We present the first infrared (IR) gas phase spectrum of a large and astronomically relevant PAH cation (CH, HBC) and its di-cation (CH,…
Photoinduced polycyclic aromatic hydrocarbon dehydrogenation: The competition between H- and H2-loss
P. Castellanos, A. Candian, J. Zhen +2
PAHs constitute a major component of the interstellar medium carbon budget, locking up to 10--20% of the elemental carbon. Sequential fragmentation induced by energetic photons lea…
Laboratory Photo-chemistry of PAHs: Ionization versus Fragmentation
Junfeng Zhen, Pablo Castellanos, Daniel M. Paardekooper +5
Interstellar polycyclic aromatic hydrocarbons (PAHs) are expected to be strongly processed by vacuum ultraviolet photons. Here, we report experimental studies on the ionization and…
Laboratory formation of fullerenes from PAHs: Top-down interstellar chemistry
Junfeng Zhen, Pablo Castellanos, Daniel M. Paardekooper +2
Interstellar molecules are thought to build up in the shielded environment of molecular clouds or in the envelope of evolved stars. This follows many sequential reaction steps of a…
C in Photodissociation Regions
Pablo Castellanos, Olivier Berné, Yaron Sheffer +2
Recent studies have confirmed the presence of buckminsterfullerene (C) in different interstellar and circumstellar environments. However, several aspects regarding C…
Dust-correlated cm-wavelength continuum emission on translucent clouds ζ Oph and LDN 1780
M. Vidal, S. Casassus, C. Dickinson +17
The diffuse cm-wave IR-correlated signal, the "anomalous" CMB foreground, is thought to arise in the dust in cirrus clouds. We present Cosmic Background Imager (CBI) cm-wave data o…
Dust-correlated centimetre-wave radiation from the M 78 reflection nebula
Pablo Castellanos, Simon Casassus, Clive Dickinson +7
An anomalous radio continuum component at cm-wavelengths has been observed in various sources, including dark clouds. This continuum component represents a new property of the ISM.…
