Next IAA lecture, Webinar, Photo contest, ISS, OM/Davagh, Fellowships, NLCs, Festival of Curiosity, Teasers, more,

Hi all,

 

(NB, all times are summer time when in force, for convenience)

 

1.  IAA LECTURE by ZOOM; Wed 21 July, 7.30 pm: "A multiwavelength view of galaxies" by Dr Maritza Lara-Lopez of AOP. 

SYNOPSIS

The formation and evolution of galaxies is intimately dependent on the conversion of gas into stars, the production of heavy elements, recycling of this material into the interstellar medium, and repetitions of this cycle. A detailed understanding of the interplay between gas mass, star formation rate, and heavy elements is clearly important to understand the galaxy evolution process. In this talk I will provide a general overview of all the different telescopes, wavelengths, and the information they provide. From the hot gas, through to the cold gas, through to star formation and back again.

Biography

Maritza obtained her PhD in 2011 from the Astrophysical Institute of the Canary Islands (IAC)  in Tenerife, Spain. Later, she moved to a research fellowship at the Australian Astronomical Observatory (AAO) in Sydney, Australia, followed by a 3 year ARC Super Science Fellowship at AAO. She then moved for 2 years to Mexico for a research position at the Institute of Astronomy at UNAM.  From 2017- 2020 she was a DARK-Carlsberg foundation fellow at the DARK Cosmology Centre, Niels Bohr Institute, University of Copenhagen, Denmark.

From August 2020 she is a STFC postdoc at Armagh Observatory and Planetarium, UK.

  Her PhD thesis won a national prize in Mexico and an institutional prize at IAC/ULL, Spain for the best thesis. In 2016 she won the L'Oreal-UNESCO prize for women in science of Mexico. She has 84 refereed publications in international journals (first author of 11), with more than 2900 citations.

2.  SPACE and ASTRONOMY WEBINARS – next one on July 20, 7.30 p.m.

NB: Note platform change. Since most people have been watching on YouTube, we are ceasing the presentation via Zoom, and it will now be streamed live on both YouTube and Facebook. This will also give us lots of added features in the presentation.

    Presented by me and the amazing Nick Howes, they are approximately 45 minutes long, every second Tuesday, at 7.30 p.m., covering whatever is topical in space and astronomy. youtube.com/spacestorelive

NB – So, from now on it will be Live streamed to YouTube SpaceStore Live! Channel and Live streamed to Facebook Live. I'll post any last minute news via Twitter.

3. IDA "Capture the Night" Astrophotography Contest
The International Dark-Sky Association (IDA) welcomes submissions to their "Capture the Night" Astrophotography contest. Photos can be submitted for free through 23 July 2021.
  Learn more here:

4. ISS. The ISS continues its series of evening passes until the end of the month. Details at www.heavens-above.com

 

5. Davagh Dark Sky Park and Observatory now open, with pre-booking, and some restrictions.

 See https://www.midulstercouncil.org/visitor/things-to-do/star-gazing/davagh-dark-sky-observatory , and https://www.facebook.com/omdarksky/ I'll post any updates here. Or phone 03000 132 132 for changing Covid-19 advice.


6. Öpik Fellowship at the Armagh Observatory and Planetarium

Armagh Observatory and Planetarium (AOP) invites applications for the newly established Öpik Fellowship, named in honor of former AOP director Ernst Öpik (1893 -1985) and his pioneering work from the study of asteroids to that of galaxies. AOP is seeking to appoint an individual on an upward career trajectory and with an outstanding research record, who is looking to establish a unique research area that would contribute to, or complement, the ongoing research at AOP. This is a unique opportunity to carry out independent research in one of the longest continuously operating astronomical research institutes in the world and one of the world's most advanced planetarium.

   For more information, see https://www.armagh.space/opportunity/opik-research-fellowship.

Closing date for applications is 16.00 on Friday 6th August 2021. 

AND

We have a PhD position available in Jonathan Mackey's group at DIAS with a fairly

wide-ranging specification, anything from data analysis of high-energy

observations to MHD simulations, as long as it is related to massive

stars.  See advertisement (or link below) for more details.

   Advertisement:        https://jobregister.aas.org/ad/3a752804

Application deadline: 11th July 2021

Start date:          Before end of 2021

Requirements:        Bachelor or Masters degree in related topic

Duration:            4 years

 

7. NLCs

There have been some great displays of Noctilucent (or 'night-shining') clouds are the highest clouds in our atmosphere, at over 80 km altitude. In the N. Hemisphere they can be seen above the northern skyline up to the 3d week of July from Ireland/UK. They are so hight that they remain illuminated by the Sun from below the local horizon, while lower clouds are in darkness.

    They form when water vapour crystallizes around specks of meteoric dust in the mesosphere when the temperature is really low. NASA scientists scientists are predicting low temperatures in the mesosphere, and so hopefully a good NLC season.

 

8. FESTIVAL of CURIOSITY, Rocket- making and Launching, Sat 24 July. See

Make your own Rocket! - The Festival of Curiosity

 

9. A: Clue for Easy Teaser  No answers for this one yet, so here's a clue - The last three gave their name to something used in astronomy, and the first one has a similar connection.

   Q. What's the connection between – A type of singing, a Keeper of the Mint, a German musician, and a Buddhist monk?

"Rules for Easy Teasers: you're barred from entering if you (A) have already submitted a correct answer to any of the previous teasers, and/or (B) if you've been a member of any astronomy clubs or societies for 15 years or more. Obviously I have to trust your honesty on that latter point, but remember, if you're correct your name will be published here, and other members of your club will see it!"

 

10. NEW (Moderately) Difficult Teaser - What's next in this sequence? A, M, A, M, P, M,  ?

 

   Please send all answers to me at my aol address terrymosel@aol.com
