3D2014: Gas and stars in galaxies: A multi-wavelength 3D perspective, ESO Garching, March 10-14, 2014
In 2008 ESO hosted the first conference on extragalactic 3D multi-wavelength astronomy (see http://www.eso.org/sci/meetings/2008/gal3D2008.html). This very successful workshop attracted more than 150 astronomers with expertise ranging from the radio to the optical wavelengths. In the intervening five-year period, 3D spectroscopic techniques have greatly extended our understanding of the key subjects addressed in this workshop.
The kinematics, mass assembly and evolution of galaxies has been explored in large samples in the optical and near-infrared by programs such as the SAURON/ATLAS3D and CALIFA surveys of nearby galaxies and the SINS and MASSIV surveys at z~1-2. 3D spectroscopy at these wavelengths has become a standard technique to such an extent that on 8-m telescopes survey style instruments have been developed. Meanwhile, for the next generation of extremely large telescopes IFU spectrographs are selected among the first instruments to be commissioned.
At the longer end of the wavelength range, the JVLA has now come online and new radio facilities are producing commissioning results. Over the last few years millimeter interferometers have produced spectacular 3D maps of carbon monoxide and various other atomic and molecular lines of galaxies out to redshifts of z=6, as well as very detailed cubes of nearby galaxies.
Against this background, it is an excellent moment to hold a second workshop in this series. The 2nd generation VLT instruments KMOS and MUSE are taking up science operations in 2013/14. ALMA is conducting Cycle 1 observations and is preparing for new observing modes and increased sensitivity and angular resolution in future Cycles. The timing is perfect to evaluate the scientific progress made since 2008 and to make the community aware of the expanding science capabilities of ESO’s 3D instrumentation suite.
Scientific topics covered at the conference will include:
- Nearby Galaxy Dynamics
- Starbursts and interacting galaxies
- Supermassive black holes and AGN
- High redshift galaxies
- Cosmology and deep fields
In addition to the science conference we will offer two half-days of parallel user workshops for MUSE, KMOS and ALMA.
The MUSE/KMOS user workshops, which will be carried out in parallel but with repeated key sessions, will include the following topics:
- MUSE/KMOS instrument status
- Observation design strategies and observation preparation tools
- Data reduction
- “Hands-on” demonstrations of selected ESO tools e.g. Observation preparation tools and data reduction pipeline
- General question and answer session(s)
- Possibly, innovative use of MUSE/KMOS
The aim of the ALMA user workshop will be very specifically to concentrate on imaging and image analysis. By March 2014 it is expected that the ALMA calibration pipeline is fully functioning. This workshop will therefore help the user with transforming their calibrated data sets into 3D cubes and images, taking them beyond what the standard imaging pipeline delivers. Topics will include self-calibration, multi-scale clean, optimal deconvolution strategies, making moment maps from cubes etc. In addition, some time will devoted to training people how to visualize their data cubes and use basic image analysis tools.
