VLT AO Community Days
Bruno Leibundgut
Background
ESO Science Priorities
Ø STC document discussed in April 2015 (STC-551)
• AO instrument on UT4 as the next VLT instrument
• ‘Select and design AO instrument’
Ø Discussion with a group of experts
• 15/16 September 2015
Ø Paranal Science Priorities (STC-561; October 2015)
• ’Discussion for the next AO instrument at the Nasmyth focus on
UT4 to make full use of the AOF has started’
Ø Planning for the next VLT AO instrument (STC-568; April
2016)
• Presented results of the expert discussion
• Proposed potential future development directions
VLT AO Community Days | 20/21 September 2016Background
STC requested community discussion
Ø ‘The STC supports the initiative described in STC-568 to
define a next generation AO instrument that can take
advantage of the revolutionary AOF facility on UT4. We
endorse the plan to hold an open meeting later this year
to fully engage with the wider community in this effort.‘
Welcome
VLT AO Community Days | 20/21 September 2016VLT AO - Current status Current VLT AO instruments cover a wide range already Ø (Julien Milli’s talk for more details) Ø SPHERE - state of the art for XAO (IR and optical) Ø NACO/ERIS - SCAO with an old system – new one in the works Ø HAWK-I/GRAAL - AOF to provide IR GLAO over 7’x7’ Ø MUSE/GALACSI - AOF to bring optical AO (750nm; 7”x7”) Ø SINFONI/ERIS - AO support of IR integral spectroscopy Ø CRIRES+ is AO supported Ø AO for VLTI (NAOMI and CIAO)

expected to be carried out for new instruments, and the overall duration is typically estimated in
6/7 years. According to the proposed scheme, New I-III are concerned by the first phase. Column

infrastructure projects (AOF, VLTI). Dates with question marks are current estimates, to be
confirmed.VLT Instrument Planning
Next instrument fully financed within the current
plan
Development and construction should be around
6 to 7 years

General agreement that this should be the AO
instrument for UT4
