Motivation:

Over the last decade, European research activities in the field of laboratory astrophysics have experienced an impressive increase in their potential to address astrophysical problems, in particular by providing essential information on the physical and chemical processes leading to chemical complexity in space resulting in star and planet formation. These activities have been motivated by the interpretation of astronomical observations obtained with single dish telescopes and short baseline interferometers. The wealth of data obtained with ALMA, space facilities (Herschel, Spitzer, Rosetta, the coming JWST, E-ELT), and other ground based observatories (VLTI, NOEMA, …), require new methodologies for the astrophysical modeling that will lead to new challenges for laboratory astrophysics.

This conference aims to address the state of the art in laboratory astrophysics within the context of these new astrophysical data and to improve communication and collaboration between astrophysicists, physicists and (geo) chemists. Hence, the conference structure will consist of invited talks presenting topics in astrophysics and planetary science and related laboratory astrophysics activities. Contributing talks will be selected to complement the topics from the astrophysical, laboratory, and theoretical/modeling points of view.

The astrophysical areas that will be addressed are:

Comets, asteroids, meteorites and the primitive Solar System nebula: formation and evolution
Protoplanetary disks and planet formation
Planet, Moon, and exoplanet surfaces and atmospheres
The signatures of the evolving interstellar medium
Dense Clouds: the gas-ice interface
Chemical fingerprints of star formation
The late stages of star evolution: dust formation
Supernovae and shocks: high-energy processing of matter

The conference will cover studies in many fields such as spectroscopy, analytical (geo) chemistry, reactivity, nanoscience, and quantum chemistry, pertaining to different matter components (gas, plasma, PAHs, ices, dust, solid surfaces, …).

Kick-off meeting

A two-day meeting (May 5 and 6, 2015) will be held at the Spain National Research Council (CSIC) headquarters in Madrid. This meeting will be focused in well targetted presentations to put forward the main goals of the project and to foster further team discussions and brainstorming. The meeting will be divided into 4 sessions covering the following topics:

  • May 5 (09:30 to 10:30) General overview of the project
  • May 5 (10:30 to 13:00) Dust formation (observations, spectroscopy, chemical modelling and nucleation)
  • May 5 (15:00 to 17:30) Dust analysis (analogs, experimental techniques)
  • May 6 (09:00 to 13:30) Dust spectroscopy (astrophysical conditions) and processes (photo/thermo-processing, gas-grain interactions)
  • May 6 (15:00 to 17:00) Technical session (engineering, vacuum)
  • May 6 (17:30 to 18:30) Summary of the PIs

The final program will be posted here when available.

Meeting place and travel

The meeting will take place at the CSIC Press Room in C/ Serrano 113 (Building 113). See both the general map around CSIC and map of CSIC headquarters. See also an underground (“Metro”) map or visit this link to consult the Madrid metro in different formats.

CSIC headquarters is pretty near both from the República Argentina (line 6) and Gregorio Marañón (line 7) metro stations. The Nuevos Ministerios metro station, which connects to all the airport terminals, is 1.5 km away. These items can be checked at the general map around CSIC above.

Metro fares can be consulted here

If you consider to take a taxi from/to the airport, please visit this site. Official taxi fares can also be consulted here.

Recommended hotels
Both the NH Breton Hotel and the NH Madrid Zurbano Hotel are located pretty near from the CSIC headquarters (1 km away). Prices for a single room are around 80 euros per night.

Gas cell for Laboratory Astrophysics (GACELA)

The Gas Cell for Laboratory Astrophysics (GACELA) consists of a stainless-steel chamber 1 meter long and a diameter of 60 cm. It is equipped with two teflon windows that allows the study of gases through rotational spectroscopy inside the chamber.

Hence, the team coupled the new NANOCOSMOS millimeter broad band receivers into the setup. These receivers are twins of those built for the Yebes 40 meter radio telescope. A series of vacuum chamber ports allow the injection of gas and liquids to perform plasma generation, ultraviolet photochemistry and optical spectroscopy. GACELA was built at the Segainvex Laboratories located at the Universidad Autónoma de Madrid.

GACELA addresses an innovative potential to perform novel experiments on plasma physics, photochemistry and ices. We also address the spectroscopical characterization of a gas injected in the cell. Thus, we performed a first set of experiments in February 2018 with the detection of CH3CN in a few seconds with a very high signal-to-noise ratio (S/N). The whole system was further improved and we have made multiple runs in the full-experimental phase from May 2018.

HEMT receivers

The 40m radio telescope at the Yebes Observatory

Outstanding publications on our innovative development

Yebes 40 m radio telescope and the broad band NANOCOSMOS receivers at 7 mm and 3 mm for line surveys (F. Tercero, J. A. López-Pérez, J. D. Gallego and 23 co-authors, A&A, 01/2021)

Breakthroughs

  • Two new cryogenic receivers for the 31.5 − 50 GHz (Q frequency band) and the 72 − 90.5 GHz (W band).
  • A new optical circuit for the W band receiver with its mirrors, new mirrors for the Q band receiver, and a new hot-cold load calibration system.
  • Instantaneous frequency coverage to observe many molecular transitions with single tunings in single dish mode: 1) Optimization of the observing time; 2) Increase in the radio telescope output efficiency; 3) Boost in data sensitivity in comparison with previous Nobeyama (Japan) 45 m telescope surveys (less than 1 mK versus 5 mK in the Nobeyama data).

Nanocosmos has developed an experimental set-up, the Gas Cell for Laboratory Astrophysics –GACELA– that operates under vacuum conditions, in order to mimick the molecular processes underlying chemical reactions of astrophysical interest. We are in particular interested in those processes occurring at the dust formation zone of AGB stars. 

We observe molecular processes in-situ by using the new NANOCOSMOS mm broad band radio astronomical receivers, which results advantageous in terms of spectral resolution and sensitivity. We have successfully applied this innovation at the 40 m radio telescope at the Yebes Observatory. Therefore, we have designed, constructed and commissioned new Q and W band receivers to foster the radio telescope capabilities and to provide wider bandwidth and better spectral resolution. The development of this instrumentation is a key aspect of the Nanocosmos project and is already providing outstanding results with the discovery of multiple molecular species.

AROMA set-up

AROMA (Astrochemistry Research of Organics with Molecular Analyzer) is a new analytical experimental set-up developed at IRAP/LCAR (Toulouse, France). The main purpose of AROMA is the study and identification, with micro-scale resolution, of the molecular content of cosmic dust analogues, including stardust analogues produced in the Stardust machine and meteoritic samples. AROMA combines laser desorption/ionization (LDI) techniques with a linear ion trap coupled to an orthogonal time of flight mass spectrometer (LQIT-oTOF).
