A repeating fast radio burst source localized to a nearby spiral galaxy

Nature, 2020
Fast radio bursts (FRBs) are brief, bright, extragalactic radio flashes1,2. Their physical origin remains unknown, but dozens of possible models have been postulated3. Some FRB sources exhibit repeat bursts4–7.

A short γ-ray burst apparently associated with an elliptical galaxy at redshift z = 0.225

Nature, 2005
Gamma-ray bursts (GRBs) come in two classes: long (> 2 s), soft-spectrum bursts and short, hard events. Most progress has been made on understanding the long GRBs, which are typically observed at high redshift (z ≈ 1) and found in subluminous star ...

A massive star origin for an unusual helium-rich supernova in an elliptical galaxy

Nature, 2009
The unusual helium-rich (type Ib) supernova SN 2005E is distinguished from all supernovae hitherto observed by its faint and rapidly fading light curve, prominent calcium lines in late-phase spectra and lack of any mark of recent star formation near the ...

IC 225: A Dwarf Elliptical Galaxy with a Peculiar Blue Core

, 2005
We present the discovery of a peculiar blue core in the elliptical galaxy IC 225 by using images and spectra from the Sloan Digital Sky Survey (SDSS). The outer parts of the surface brightness profiles of u-, g-, r-, i-, and z-band SDSS images for IC 225
