An Overwhelming Sense of Discovery

Jose Vargas ’15 is a time traveler.

As an undergraduate researcher in professor John Wardle’s lab, Vargas studies quasars, the brightest and most remote objects in the universe, clocking in at 10 to 12 billion light years away, meaning Vargas is looking 10 to 12 billion years in the past.

Quasars form when supermassive black holes — billions of times the mass of the Sun — feed on nearby material. The matter forms an accretion disk around the black hole, heating up to millions of degrees and blasting out radiation and powerful jets of particles, traveling at nearly light speed — like the universe’s largest particle colliders.

Astrophysicists believe that quasars may be an important step in the birth of galaxies.

We asked Vargas to describe what it’s like to see into the past. Here is what he said:

Wandering the stars with the Brandeis Astronomy Club

The Brandeis Astronomy club, led by Isaac Steinberg, meets several times a month to observe and photograph the cosmos. Here are a few of their snapshots:

Jupiter has the shortest day of all the planets in the solar system. It turns on its axis once every 9 hours and 55 minutes, spinning so quickly that the planet  is slightly flat, giving it an oblate shape.

The moon is rotating in synchrony with the earth, known as tidal locking. As a result we can only see the nearside of the moon from earth, which is a bit more than half of the moon given oscillation in its orbit.

The Andromeda Galaxy  is the nearest spiral galaxy to the Milky Way, which is also spiral galaxy. It has an approximate trillion stars to our puny 300 billion. This image was composed of 8 long exposure photos, which were then merged to pull out detail and remove noise.

The Albireo star system in the center is in the constellation Cygnus. The larger of the double star is a binary star system composed of two stars that orbit each other. The larger star appears yellow and the smaller one blue when resolved with a telescope.

Saturn, the sixth planet from the sun and the second largest in the solar system, is comprised mostly of helium.

So you want to work in a lab? Abby Knecht ’15 offers some advice

Dear freshmen,

You probably learned about RNA transcription in high school but have you ever seen it in action? I spent my summer watching, in real time, as small sections of DNA were converted into RNA for gene expression.

I work in a biochemistry lab at Brandeis that studies transcription under special fluorescent microscopes that allow us to observe single molecules interacting. It’s an incredible feeling to be able to see and study something that is so fundamental for life itself but hidden from our everyday view.

Working in a lab is unlike any science course you’ve taken so far. Science is about puzzles.  It’s about looking at the world, asking questions and finding ways to uncover the answers to those questions. But as one answer is found, more questions invariably pop up and the process continues.

Some of you may find this uncertainty frustrating, and long for the hard facts of lectures. Others may find that you enjoy discovering new things — things no one else has seen and are glad that memorization is not required. Others (like myself) may find that you like science in all its forms and enjoy both.

Whatever group you fall into, you won’t know until you try working in a lab.

Working in a lab is the best way to see how science is really done. You’re on the frontier of discovery. Unlike high school, where lab results are often spoon-fed to you, no one knows what the results will be: that’s why you’re doing the experiment.

Brandeis is a great place for undergraduate research. There are a lot of research labs and undergraduates have a chance to step up and perform their own research. I recommend anyone even remotely interested in science to try working in a lab.

If you want more help applying for labs or deciding whether or not to try it, I advise talking to Hiatt, our on-campus career center, your adviser, or the undergraduate department representative (UDR) in your field of interest.

Good luck!
