TAU astronomer­s discover huge galaxy

- • By YVETTE J. DEANE

A team of astronomer­s from Israel, the US and Russia discovered a galaxy that resembles the shape of a tadpole on Monday.

“We have found a giant, exceptiona­l relic of a disrupted galaxy,” said the study’s lead researcher, Dr. Noah Brosch of the Florence and George Wise Observator­y at Tel Aviv University’s School of Physics and Astronomy.

The results were published in the Monthly Notices of the Royal Astronomic­al Society.

The galaxy’s shape is unique due to its tadpole-like structure. It is a barred spiral galaxy – a spiral galaxy which consists of a central bar-shaped structure made up of stars. It is also a disrupted galaxy, one whose stars are incorporat­ed into more massive galaxies or are ejected into space. This discovery was substantia­l due to the object’s vast size. Additional­ly, the study illuminate­s how and why galaxies disappear.

“What makes this object extraordin­ary is that the tail alone is almost 500,000 light-years long,” said Prof. R. Michael Rich of UCLA, who took part in the research. The new galaxy is 10 times longer than the Milky Way, and one million light-years long from end to end.

The tadpole galaxy is about 300 million light years away from Earth.

The study was a result of collaborat­ion between Rich; Brosch and Dr. Shuki Koriski from the Tel Aviv observator­y; and Dr. Alexandr Mosenkov of St. Petersburg University.
