#ESOz2020 Day 4. Starting at 9am sharp (& me walking around to get the watch movement tick this hour) with Matt Jarvis giving the review talk “Galaxy populations across time and wavelength”
Ah, yes, the webpage combining the thread for #ESOz2020 Day 3 is here:…
In this talk it has been mentioned again LSST (several times during #ESOz2020 mentioned) but please everyone remember that it is now the “Vera Rubin Observatory” @VRubinObs in honour to this great woman astrophysicist… #WomenInScience
Matt Jarvis also provides an overview of how we observe galaxies at radio wavelengths with the cosmic time #ESOz2020
Matt Jarvis summary slide and multi-wavelength surveys of deep extragalactic fields in the near future #ESOz2020
Next Imogen Whittam @imogenwhittam presents “The MIGHTEE continuum survey” conducted at the MeerKAT radio interferometer in South Africa. Amazing radio data, perfect for addressing some important science issues about galaxy evolution #ESOz2020
Imogen Whittam @imogenwhittam discusses “Why is MIGHTEE mighty”, shows amazing deep MeerKAT radio observations in the COSMOS field. They study how does AGN activity affect galaxy evolution. Conclusions slide included #ESOz2020
Now Benjamin Quici @ICRAR talks about “Dying radio galaxies in GAMA 23”. Radio lobes (yellow in last slide) and galaxy cores (green) have very different radio behaviour #ESOz2020
Now Nick Seymour @ICRAR talks about “Evolution of the Low Frequency Radio-loud AGN Population” #ESOz2020. I love the “sophisticated simulation” included as example (video not shown here, a little girl blowing bubbles) for explaining radio jets
Conclusion slide at the end of Nick Seymour @ICRAR talk #ESOz2020
Next is great @astro_katross Kathryn Ross @ICRAR who confesses this is her very first science talk in an international conference! That is perhaps she was that serious while waiting to start talking? And remember: #IncludeHer ! #ESOz2020
Kathryn Ross @astro_katross @ICRAR studies peaked-spectrum radio galaxies using the GLEAM survey ... and she is finding Unexpected Spectral Variability... what is that? #ESOz2020
Now @astro_katross @ICRAR discusses possible suspects to the observed spectral variability: 1. Scintillation 2. Blazars (but that also does 1) and 3. Weirdos (sorry, phone decided to defocussing camera) #ESOz2020
Conclusion by @astro_katross @ICRAR: mystery is UNSOLVED, they need more data. Another unsolved mystery: why women physicists are not included in NSW curriculum? Sign #IncludeHer, also listen @AstroKirsten & me interviewing Kat in @theskyentists #ESOz2020
After morning coffee break Helmut Dannerbauer @IAC_Astrofisica gives the highlight talk: “Impact of environment on molecular gas reservoirs probed in distant cluster and field galaxies” #ESOz2020
Helmut Dannerbauer @IAC_Astrofisica & his team uses the CO(1-0) emission detected at redshift 2 using the fantastic @CSIRO_ATNF Australia Telescope Compact Array, they are conducting the COALAS (CO ATCA Legacy Archive of Star-forming galaxies) large program #ESOz2020
Some nice results with CO(1-0) detections in galaxy protoclusters (clusters in formation, but not official definition) using @CSIRO_ATNF ATCA shown by Helmut Dannerbauer @IAC_Astrofisica and his conclusions #ESOz2020
Next Amanda Wilber @ICRAR presents “Searching for diffuse radio emission in merging galaxy clusters with LOFAR and ASKAP” #ESOz2020
Amanda Wilber @ICRAR provides an overview of radio sources in galaxy clusters, synchrotron spectrum helps studying these radio sources. Why study them? #ESOz2020
Amanda Wilber @ICRAR and her team use both the LOFAR and @CSIRO_ATNF ASKAP radio-interferometer to study the synchrotron spectrum of radio sources. In the near future large radio surveys will allow them to do statistical studies #ESOz2020
Next Anishya Harshan @UNSWScience talks about “Star formation histories for a z~2 proto-cluster with PROSPECTOR”, which is a Python-based spectral energy distribution (SED) fitting code. Summary slide included #ESOz2020
Now Edo Ibar talks about “The molecular gas and dust content in ‘typical’ star-forming galaxies at z = 1.46 & 2.23 as revealed by @almaobs#ESOz2020
Edo Ibar describes that they are combining SINFONI/VLT @ESO + @HubbleTelescope + @almaobs observations of galaxies at redshift ~ 1.5! #ESOz2020
Edo Ibar also compares the gas dynamics as observed by ionised (optical) and molecular (radio) gas and check the Schmidt-Kennicutt law at z~1.5 #ESOz2020
Now Ruby Wright @RJWright25, PhD candidate at @ICRAR supervised by @CDPLagos & Chris Power, talks about “Baryon inflow to halos: insight from hydrodynamical simulations” #ESOz2020
More results and summary of the research that Ruby Wright @RJWright25 @ICRAR is conducting about the baryon inflow to halos using simulations #ESOz2020
Now Sabine Bellstedt @SabineBellstedt @ICRAR talks about star-formation histories of galaxy populations using the SED-fitting code ProSpect using the GAMA data #ESOz2020
Fantastic presentation & great results by Sabine Bellstedt @SabineBellstedt @ICRAR who emphasises A LOT the importance of METALLICITY for getting right the star-formation histories #ESOz2020
Sabine Bellstedt @SabineBellstedt @ICRAR check carefully the metallicity evolution for each of the GAMA galaxies when doing the SED fitting, now she is able to obtain the cosmic star-formation history right!! #ESOz2020
Sabine Bellstedt @SabineBellstedt @ICRAR can now study cosmic star-formation AND the mass-metallicity evolution, beautiful results!! #ESOz2020
Let me also share with you this slide I sometimes use to remember everyone that knowing the METALLICITY IS IMPORTANT for understanding galaxy evolution! Thanks Sabine Bellstedt @SabineBellstedt @ICRAR for being so clear there! #ESOz2020
After lunch Daniel Ceverino @UAM_Madrid gives the review “Simulations at the Dwarf Scale: From Violent Dwarfs at Cosmic Dawn and Cosmic Noon to Quiet Discs today” #ESOz2020
Evolution of the gas kinematics from Daniel Ceverino et al. models, they find a weak evolution of the mass-metallicity relation at cosmic dawn. Summary slide included. #ESOz2020
Next Martin Zwaan @eso talks about “Surveying the Universe with ALMACAL”, in brief, using the calibrator data obtained by @almaobs for science #ESOz2020
Now Aleksandra Hamanowicz @ESO explodes the @almaobs ALMACAL data to conduct a blind search for CO emission #ESOz2020
Unfortunately yesterday I had to skip some #ESOz2020 sessions as I needed to work on something else. But @astro_katross has us covered, she tweeted some of the talks
The talk I really wanted to attend was by Elisabete da Cunha @ICRAR. @CDPLagos tweeted some photos & comments #ESOz2020
However, the combination of tiredness & shyness (see ) made me decided to also skip #ESOz2020 Conference Dinner :(
(I think the “d” in “decided” should not be there, sorry, fast typing)
I know coffee breaks, lunches & conference dinners are important for #networking & strength research collaborations but (I’m not sure if it is the age) every year I’m feeling more “out of place” there. #ESOz2020 CD was great though photo: @PhillyPatterson
Anyway, let’s move on... @threadreaderapp unroll please!
