Since the amount of dark energy directly impacts the expansion of the Universe, we can also try to estimate the distances which contain information about the expansion history 📏📐. I'm an observational astrophysicist, mostly working on near-field cosmology, Galactic archaeology, and metal-poor stars. The two images are of a nearby galaxy called M82...can you spot the difference? Date Published.

Instead of relying on crowdsourced classification, the researchers used knowledge from the state-of-the-art Xception neural network, combined with the datasets generated by the Galaxy Zoo project, to train its deep learning models. I completed my undergraduate at Fudan University in Shanghai, China, ... Ting Li . We’ll share here when we release the final ta-da ✨ , and we have lots more planned in the coming days to communicate what we’ve done to you all, so stay tuned! Around 7000 clusters were detected in the first year of data of DES. Pasadena, CA— A team of astronomers including Carnegie’s Ting Li and Alexander Ji discovered a stellar stream composed of the remnants of an ancient globular cluster that was torn … I am the 2019 NASA Hubble Fellow (short bio) at Carnegie Observatories. and the HETDEX project, etc. Ting Li . Texas A&M-Led Astronomy Research Details Unprecedented Life Story of Milky Way Galaxy Evolution. Maybe you don’t feel that you are gaining new knowledge every day, or maybe you feel that you are standing still after many days of hard work. Since this idea was first proposed, we’ve conducted decades of research to better understand what dark energy is, how much of it there is, and how it influences our universe. It is a visitor from a strange land,” said Dr. Ting Li, from Carnegie Observatories and Princeton University. ... See MoreSee Less. ⁉️What is the geometry of the Universe on the largest scales?

An extensive analysis of four different phenomena within the universe points the way to understanding the nature of dark energy, a collaboration between more than 100 scientists reveals. These monsters can weigh as much as one million of billion times the mass of our Sun ☀️ ! Sky survey with CCDs, starting from SDSS. with a major in Physics and a minor in Diplomacy. We measure this distance at different times in the history of the universe to infer how the expansion evolved! To explain this phenomenon, we invoke what’s known as dark energy — an unknown form of energy that exists everywhere and exerts a negative pressure, driving the expansion. Problems with classical methods for extracting information from the full spectra such as the Dark Energy Survey (DES). Since the amount of dark energy directly impacts the expansion of the Universe, we can also try to estimate the distances which contain information about the expansion history. The “workspace of the future,” Carnegie’s VizLab will unlock the secrets of the universe. weeks, as we broke down the key steps 🔑 in our cosmological analysis 🔭 , and big thanks to @astroalexamon @cosmologirl and @nfmcrn for creating bite-sized pieces 🧩 . In particular, I am building the focus and alignment system for DESI, which is an essential component for the survey commissioning and operation. Or will it crunch back in on itself? edu Phone: (626) 304-0253 Independent, Q&A with Graduate Student Ting Li ’16. a Joint European Master in Space Science and Technology (SpaceMaster), Carnegie Observatories. We call a certain subset of  them standard candles 🕯 : we know roughly how much light they release, so their observed brightness tells us how far away they are.
