Queer astronomers everywhere: help me out!

I am a producer on the Cosmos From Your Couch team from the @DunlapInstitute. We’re putting together a feature video of LGBTQIA2S+ astronomers to release during Pride Month and we would like your help!

[Victor Chan @Viithinks]

@cosmic_mar @reneehlozek We are also exploring a direct comparison of methods with a likelihood. This will look like the P(Cℓκκ | CℓΨ) you are suggesting, or also like P( theta | CℓΨ) for particular models. It would be really exciting to see how this would compare with full Bayesian lensing!

[Victor Chan @Viithinks]

@cosmic_mar @reneehlozek Thank you for sharing your thoughts! Your interpretation of SCALE/HDV noise is fair, along with SCALE being an indirect estimate of κκ. In other words, it's the statistical scatter we expect from applying SCALE/HDV to a particular lensed CMB realization of similar map area.

Way to go @Viithinks!!

[Dr./Prof. Renée Hložek @reneehlozek]

I’m delighted to share the @DunlapInstitute “graduate student of the month”, @Viithinks who is my student (co-supervised with the uber-talented @jobovy). https://t.co/UJ187Phdm9 Victor is a great member of the #hnauts and doing awesome work on #cosmology inference and analysis!

Folks, this is the reality of #Starlink.

My heart literally just sank into my stomach. I used DECam as a member of @theDESurvey for 5 years. This is horrifying.

If you're still wondering what the controversy is over these satellites, this is only part of it.

Excited to announce the new version (v1.5) of galpy!

Thank you @akkagawa for this article. As a Mi'kmaq person and astronomer, I struggle with the question of how I talk about astronomy and STEM to Indigenous youth. https://t.co/sEsY1tbKKx

[Victor Chan @Viithinks]

Things are about to get started at KITP for the #KITP_H0Takes conference!

Stonk tip of the day

[Ayushi Singh @AyushiAdAstra]

Presented my poster at #CASCA2019 using the #betterposter design by @mikemorrison

[Dr. Megan Tannock (she/her) @AstronomerMegan]

Carl Ziegler at #CASCA2019: the 0.5m One Hit Wonders telescope will follow up single-transit @NASA_TESS detections.

[Victor Chan @Viithinks]

Fellow #hnauts member @tinapeters tells us how to deal with problems that come up with determining photometric redshifts. #CASCA2019

[Victor Chan @Viithinks]

The development of a multitapered Lomb-Scargle periodogram allows for low-bias estimates of power spectral densities especially for unevenly sampled data

[Victor Chan @Viithinks]

@GwenEadie to speak about new approaches to time-domain astronomy. #CASCA2019

[Victor Chan @Viithinks]

Looking at time series of star brightnesses can tell us about their inner workings, but there are some challenges to that

[Victor Chan @Viithinks]

@TomasCassanelli will tell us about VLBI between CHIME and the Algonquin Radio Observatory. #CASCA2019
