Thread by @El_Lobo_Rayado

The main reason I’ve been quite off from social media lately is the #AusESO2019 conference, organised by @AAOMacquarie @AAOorg @ESO_Australia et al, starting now.After enjoying 1h40min of driving in Sydney I got in time for listening Eric Emsellem @ESO, connecting Australia & ESO

PS: GPS said “45 min” when I departed from “home” this morning...

Next in #AusESO2019 is Julia Bryant @Sydney_Science @AAOorg talking about 🇦🇺 Integral Field Spectroscopy and synergies with @eso, first showing showing some results from @SAMI_survey. And that is me at the AAT plugging SAMI fibres!

Julia Bryant @Sydney_Science @AAOorg @ARC_ASTRO3D next describes the need of an IFS galaxy survey larger than @SAMI_survey : this will be HECTOR, that will take major dark time at the AAT in the next years to conduct unique galaxy science #AusESO2019

Hexabundles in HECTOR will have up to 30” in size to cover ~2Re in galaxies, helping understand better key galaxy parameters. It will also get auxiliary data in optical, IR and radio (HI using @WALLABYsurvey at @CSIRO_ATNF ASKAP). Julia Bryant @Sydney_Science @AAOorg #AusESO2019

After the coffee break, #AusESO2019 is back with Luke Davies @ICRAR talking about galaxy evolution with the next generation of redshift surveys. After providing overview of what’s done, Luke describes @TaipanSurvey very soon starting at the UKST using @AAOMacquarie starbugs

Luke Davies @ICRAR discusses @wavessurvey and @devilsurvey as galaxy surveys aiming to understand key questions for galaxy/environment evolution, emphasising the need of exploring low-mass galaxies #AusESO2019

But both @wavessurvey & @devilsurvey will also explore galaxy evolution trying to understand the astrophysics that shaped the local galaxy population, for this also using multi-wavelength data. Luke Davies @ICRAR in #AusESO2019

Next in #AusESO2019 conference is Lister Staveley-Smith @ICRAR talking about @WALLABYsurvey to be conducted at the ASKAP @CSIRO_ATNF

#AusESO2019 Lister Staveley-Smith @ICRAR presents some early science results of the @WALLABYsurvey, including latest paper by @KarenLeeWaddell about the interesting neutral gas distribution in the NGC 7232 galaxy group. Plenty of interactions & individual HI clouds found!

Next at #AusESO2019 is Joel Vernett @ESO summarising ESO’s current and future instrumentation. First describing VLT instruments at the 4 UTs... but UT4 is special as can use adaptive optics (AO) improving the spatial resolution!

Joel Vernett @ESO describes powerful MUSE IFS instrument at UT4 of VLT, now also using AO & narrow field. Also Hawk-I, very soon ESPRESSO for searching rocky planets at UT4 of VLT #AusESO2019

More info about current & future instruments at @ESO telescopes by Joel Vernett at #AusESO2019 (I)

More info about current & future instruments at @ESO telescopes by Joel Vernett at #AusESO2019 (II), also including HARMONI for the ELT !

Now Magda Arnaboldi @ESO talks about current & future ESO surveys at the #AusESO2019 Conference. For the VST 3 surveys have been completed: KIDS, ATLAS and VPHAS+

Magda Arnaboldi @ESO talks about current & future ESO surveys #AusESO2019. Almost all surveys at VISTA are completed (only VHS close to finish soon). More VISTA surveys coming soon, some highlights of current @ESO imaging surveys are shown.

Magda Arnaboldi @ESO now presents spectroscopic ESO surveys #AusESO2019, some highlights are discussed, remarking observing the first light from a gravitational wave source, the famous #kilonova found in NGC 4993 in August 2017

Magda Arnaboldi @ESO discusses the return for the community of the @ESO Public Surveys and the forward look, including the new ESO Archive Science Portal #AusESO2019

Last talk before lunch break at #AusESO2019 is Richard McDermid @MQPhysAstro @MQSciEng @Macquarie_Uni talking about MAVIS: an Australian-led facility for the @ESO VLT

Richard McDermid @MQPhysAstro @MQSciEng @Macquarie_Uni: MAVIS will provide comparable sensitivity to JWST and ELTs, but with higher angular resolution. Some examples shown #AusESO2019

More examples about what to expect from MAVIS shown by Richard McDermid @MQPhysAstro @MQSciEng @Macquarie_Uni in #AusESO2019

Scott Croom @Sydney_Science @ARC_ASTRO3D summarises main results obtained using the @SAMI_survey at the 3.9 Anglo-Australia Telescope at #AusESO2019

Remso van der Burg @ESO talks about ultra-diffuse galaxies (UDGs) at the #AusESO2019 Conference, including what do we know and what we need to know.

One of the UDGs studied by Remso van der Burg @ESO & colleagues is NGC 1052-DF2, “the galaxy lacking dark matter”. New data with MUSE VLT, nice spectra, confirmed it has a low total mass for its stellar mass #AusESO2019

Garry Foran @Swinburne talks about deciphering the evolution of galaxy kinematics and large scale structure over cosmic time using observed Lyman-alpha relationships at #AusESO2019

Next Mireia Montes @UNSWScience @mireiamontesq explores the fossil record of galaxy evolution in clusters using intracluster light (ICL). This informs about accretion history & dynamical evolution of the cluster as well as properties of underlying dark matter halo #AusESO2019

Mireia Montes @UNSWScience @mireiamontesq emphasises how to use ICL as tracer of dark matter (DM). She & her team have successfully done it in several galaxy clusters. This technique seems to be more efficient than gravitational lensing for tracing DM in clusters! #AusESO2019

Next Alessandro Sonnerfeld presents a Hyper Suprime-Cam view of the CMASS galaxy sample in #AusESO2019 (I still don’t know what CMASS is)

Too many cool images & info to be able to summarise here in a tweet... Annalisa Pillepich during her #AusESO2019 talk (II)

Next in #AusESO2019 is Tomoko Suzuki talking about spatially resolving star-forming regions within galaxies in a dense proto-cluster core at redshift z=2.53

Day 2 of the #AusESO2019 Conference. Nick Seymour @ICRAR talks about galaxy formation and evolution in the Early Universe using radio observations, which provide an unique probe as trace star-formation and galaxy jets from AGNs across cosmic time

Nick Seymour @ICRAR talking in #AusESO2019: radio observations are unique tracer of star formation but require improved understanding. Radio AGN can affect the host galaxy and local inter-galactic medium (IGM) an inter-cluster medium (ICM), hence galaxy feedback

Now Bitten Gullberg @durham_uni talks about high-resolution ALMA @almaobs imaging of SMGs. SMGs stands for “sub-millimetre galaxies”, objects in the distance universe that are thought to be experiencing a strong star-formation event, as local luminous IR galaxies #AusESO2019

Interesting: the analysis of sub-millimetre galaxies using @almaobs imaging by Bitten Gullberg @durham_uni & team suggests that dust emission traces bars which funnel cold gas into galaxy centres fuelling star-formation, no galaxy mergers as happens in local ULIRGs #AusESO2019

Next Gabriele Pezzulli talks about constraining feedback models with Giant Ly-alpha nebulae at z~3 #AusESO2019

Gabriele Pezzulli and team use MUSE VLT @ESO for observing Giant Ly-alpha nebulae at z~3 and use data for constraining number of baryons in the circumgalactic medium (CGM) #AusESO2019

After the lunch, we are back in #AusESO2019 conference with amazing Bärbel Koribalski @HIgalaxies @CSIRO_ATNF talking about star formation in galaxies, emphasising the importance of getting radio observations of galaxies to trace the cold gas in & around

A great example for understanding this is nearby galaxy M83: deep images already shown “light” far from the galaxy, UV images revealed SF in outskirts, LVHIS data by Bärbel @HIgalaxies showed plenty of cold gas outside M83. Nice multi-wavelength image ;-) #AusESO2019

Some few more examples: NGC 1512/1510, work that Bärbel @HIgalaxies @CSIRO_ATNF & me have done together and @lellifede study in the formation of tidal dwarf galaxies #AusESO2019

And now it is the turn for the @WALLABYsurvey at the ASKAP to get resolved diffuse gas maps of nearby galaxies. Bärbel @HIgalaxies @CSIRO_ATNF shows some early science results, much more to come soon! #AusESO2019

Now Deanne Fisher @Swinburne presents DYNAMO: an up-close view of turbulent, clumpy galaxies #AusESO2019
