Hawaii, Chile, Mike discussed on Scientific Sense

Scientific Sense


Mike duties purposive. Philip mouse calls who has joined appointment at arizona state university in the school of earth and space exploration and the department of physics his back now distant primarily experimental cosmology in particular deciding a good thing new types of instruments for measuring signals from the most distant objects in the numbers buckle phil. Thank you nice to be here. Thanks doing this. I want to start with. What if your people from twenty eighteen Billy bates grave. Polite to using kinetic inductions detectors for told tech. I don't know if that's pronounce that day. And beyond so before we get the details of this. What exactly is protected. Call that day. Yes sure yeah. Toll tech is. It's the name it's named after a you know a group of the native group of in mexico and it's named that because The the the what it is is it's a camera at millimeter wavelengths that we have been building for a telescope in mexico which is called the large millimeter wave telescope or l. m. t. or in in mexico. It's the grand telescope Metric or cake day at and It's it's it's the mexico has actually a really strong background. Historically in astronomy like from the Early civilization and this telescope project which was started a decade ago. Maybe actually more. Like twenty years ago was still i think. The largest scientific project in mexico was building the telescope which is a fifty meter diameter telescope on top of sierra negra which is fifteen thousand foot mountain in the middle of mexico and so totake is is a camera that we're building using the latest superconducting technology or to go onto that telescope and make measurements location-wise Obviously will get into people but Mexico because it's a near the topics evident It has elation so what what is of the primary capital states Authentication yeah well. The primary characteristics are Allocation you know for a astronomy. And i know you've had other people on who also work as i do with telescopes and other places like chile or hawaii so so basically what you want. Is you want to be as you know. As high as possible to be above the atmospheric water vapor and that's the main The main component of the atmosphere that That absorbs millimeter. Wave light so So mexico it turns out has a fairly high mountains including pico. Or it's about or. I think it's called seat loyalty pedal which is right next to serra negra mountain which and that. One is the tallest mountain in central america. It's a nineteen thousand feet or so almost and so the mountain that it's on fifteen thousand feet. So that's that's what you want. Also it's it's a good latitude so it's nineteen degrees north latitude. Which is the same pretty much the same latitude as hawaiian. It gives you good access to most of the sky. So if you're too far north you can only see the northern stars two thousand southern stars so Good good position to and The millimeter size Vive linked what this target. What what sort of the primary target. Yeah so there's there's a couple but millimeter wavelengths so it's long a thousand times longer wavelength than the light that you see with your eye the optical which is just short just smaller than a micron wavelength and and so what we're looking at is Light from either from the early universe leftover from from from the early universe which has peaks at wavelengths around one millimetre. So that's one of the things we can look at and then the other main sources of emission or might at millimeter wavelengths are on gas and dust in the universe mainly in galaxies our own galaxy. So where where..
