UChicago scientists first X-rays mystery supernovas
2017/9/5
Exploding stars lit the way for our understanding of the universe, but researchers are still in the dark about many of their features.A team of scientists, including scholars from the University of Ch...
UCLA astronomers make first accurate measurement of oxygen in distant galaxy
UCLA astronomers first accurate measurement of oxygen galaxy
2016/8/11
UCLA astronomers have made the first accurate measurement of the abundance of oxygen in a distant galaxy. Oxygen, the third-most abundant chemical element in the universe, is created inside stars and ...
CWRU astronomers find new details in first known spiral galaxy
CWRU astronomers first known spiral galaxy
2015/3/4
Case Western Reserve University astronomers peered deep into space to discover new features of a galaxy that’s been sketched and photographed for 170 years.
The researchers were able to see faint plu...
CO luminosity functions for far-infrared- and B-band-selected galaxies and the first estimate for Omega(H I+H2)
surveys molecules
2014/12/24
We derive a nonparametric CO luminosity function using an FIR- and an optical B-band-selected sample of the galaxies included in the FCRAO Extragalactic CO Survey. The FIR-selected sample is defined u...
A first estimate of the baryonic mass function of galaxies
luminosity function mass function
2014/12/24
We estimate the baryonic (stellar+cold gas) mass function of galaxies in the local universe by assigning a complete sample of Two Micron All Sky Survey and Sloan Digital Sky Survey galaxies a gas frac...
When, and how, did the first galaxies and supermassive black holes (SMBH) form, and how did they reionization the Universe? First galaxy formation and cosmic reionization are among the last frontiers ...
PACS and SPIRE photometer maps of M 33: First results of the HERschel M 33 Extended Survey (HERM33ES)
M 33 Simple isothermal
2014/12/22
Context. Within the framework of the HERM33ES key program, we are studying the star forming interstellar medium in the nearby, metal-poor spiral galaxy M 33, exploiting the high resolution and s...

2014/3/17
University of Hawaii at Manoa astronomer Regina Jorgenson has obtained the first image that shows the structure of a normal galaxy in the early universe. The results were presented at the winter Ameri...
The first IRAM/PdBI polarimetric millimeter survey of active galactic nuclei. II. Activity and properties of individual sources
IRAM/PdBI polarimetric millimeter survey properties individual sources
2012/2/21
We present an analysis of the linear polarization of six active galactic nuclei - 0415+379 (3C~111), 0507+179, 0528+134 (OG+134), 0954+658, 1418+546 (OQ+530), and 1637+574 (OS+562). Our targets were m...
The Small Isolated Gas Rich Irregular Dwarf (SIGRID) Galaxy Sample: Description and First Results
Small Isolated Irregular Dwarf Galaxy Sample: Description First Results
2011/10/12
Using an optically-unbiased selection process based on the HIPASS neutral hydrogen survey, we have selected a sample of 83 spatially isolated, gas-rich dwarf galaxies in the southern hemisphere with c...
Observations of the most distant bright quasars imply that billion solar mass supermassive black holes (SMBH) have to be assembled within the first eight hundred million years. Under our standard gala...
