Revealing the Recycled inflow of the massive galaxies at high redshift
high redshift massive galaxies Recycled inflow
2023/6/19
The gas surrounding galaxies is known as the circumgalactic medium (CGM) which is considered to be deeply coupled with the evolution of galaxies. Although lots of works have been done, how galaxies co...
Galaxies eventually undergo a phase in which they lose most of their gas, which results in a change into their properties over the course of their evolution. Current models for galaxy evolution sugges...

How fast is the universe expanding? Galaxies provide one answer(图)
universe expanding Galaxies answer
2021/4/9
Determining how rapidly the universe is expanding is key to understanding our cosmic fate, but along with more precise data comes a conundrum. Estimates based on measurements in our current universe d...
Sky survey reveals newborn jets in distant galaxies(图)
Sky survey newborn jets distant galaxies
2020/12/11
Astronomers using data from the ongoing VLA Sky Survey have found distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material w...
Galaxies grow by accumulating gas from their surroundings and converting it to stars, but the details of this process have remained murky. New observations, made using the Keck Cosmic Web Imager at th...

Supermassive Black Holes Control Star Formation Large Galaxies
2018/1/10
Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy evolves. A new study, published January 1, 2018, in Nature, shows that the mass...

Observations of two galaxies made with the National Science Foundation-funded Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope suggest that large galaxies formed faster than scienti...
Quasars may answer how starburst galaxies were extinguished
Quasars answer starburst galaxies extinguished
2017/9/1
Some of the biggest galaxies in the universe are full of extinguished stars. But nearly 12 billion years ago, soon after the universe first was created, these massive galaxies were hotspots that brewe...
Milky Way-like Galaxies in Early Universe Embedded in 'Super Halos'
Milky Way-like Galaxies Early Universe Embedded Super Halos
2017/3/30
By harnessing the extreme sensitivity of the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only e...
Astronomers observe early stages of Milky Way-like galaxies in distant universe
Astronomers early stages Milky Way-like galaxies distant universe
2017/3/30
For decades, astronomers have found distant galaxies by detecting the characteristic way their gas absorbs light from a bright quasar in the background. But efforts to observe the light emitted by the...
Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milk...
