At 
the 
University 
of 

Michigan, a professor in the 
Department of Astronomy is 
taking the phrase “reach for the 
stars” to a whole new level.

In 
a 
new 
discovery, 

Astronomy Prof. Sally Oey and 
her team observed runaway 
stars using Gaia, a new satellite 
launched 
by 
the 
European 

Space Agency.

“What we were originally 

trying to do was look for 
runaway stars and those are 
massive stars,” Oey said. “So 
they’re moving really fast and … 

this satellite is able to see very 
tiny motions of stars in the sky 
with extreme accuracy.”

LSA junior Johnny Dorigo 

Jones has been working with 
Oey monitoring runaway stars 
for a year. He said his primary 
role was to synthesize the 
data and construct pictorial 
representations of the findings.

“My main role with this 

paper was working with all the 
data from Gaia and creating the 
image showing all of the arrows 
that you might have seen in one 
of the press releases,” Dorigo 
Jones said.

Oey said the new satellite is 

able to detect the motions of 

stars in a smaller companion 
galaxy of the Milky Way around 
150,000 light years away. The 
new technology, she explained, 
will shed a new light on the 
studies of the Milky Way and 
other galaxies.

“I think this new telescope, 

in particular, is something that 
has really revolutionized our 
view of our own galaxy and in 
nearby galaxies because we can 
really see the stars as objects 
that are in motion now,” Oey 
said.

During her research, Oey 

said her team noticed how one 
section of a satellite galaxy was 
moving in the same direction 

and wanted to consult 
outside help to investigate 
the astronomical finding.

“We were like ‘Woah, 

what is that?’” Oey said. 
“When all of those stars in 
one section of the galaxy 
are moving together in 
one direction, so that’s 
when we got in touch 
with this professor at the 
University 
of 
Arizona, 

Gurtina Besla.”

Besla is an associate 

professor 
in 
the 

Department of Astronomy 
and Steward Observatory 
at 
the 
University 
of 

Arizona, 
focusing 
on 

theoretical 
astrophysics 

and 
galaxy 
formation. 

In 
conjunction 
with 

Oey, Besla modeled the 
interaction between the 
two satellite galaxies. 

“She’s 
modeled 
the 

interaction of these two 
galaxies 
and 
she 
had 

predicted back in 2012 
that the two Magellanic 
clouds 
galaxies 
should 

have collided with each 
other,” Oey said.

Oey said if these two galaxies 

had a direct collision, then the 
smaller Magellanic cloud stars 
would be gravitationally drawn 
to the large Magellanic cloud — 
this is what the research team 
observed.

“So these observations are 

actually confirming her theory, 
her prediction, that these two 
galaxies have had a direct 
collision,” Oey said. “We were 
originally interested in looking 
for the runaway stars but this 
was just something that we 
happened to see and it was a 
very very cool result.”

LSA freshman Max Resnick 

said though he doesn’t know 
much about astronomy, he finds 
the research fascinating and 
ground-breaking.

“Though it might not directly 

affect us that two galaxies 
collided hundreds of millions of 
lightyears away, it’s still really 
cool to think about something 
that grand and happening in 
our universe,” Resnick said.

Jones said he was excited 

by the confirmation of some of 
Professor Besla’s predictions by 
kinematic evidence from the 
Gaia telescope.

“It’s 
always 
cool 
when 

the simulations and actual 
observations 
can 
line 
up,” 

Dorigo Jones said. “It’s really 
cool that we were able to use this 
data from the new very accurate 
telescope Gaia to confirm some 
of these predictions.” 

According to Resnick, new 

discoveries can be beneficial to 
many, not just astronomers.

“I would say there are some 

things in any science which 
can be applied to other sciences 
that might be more directly 
impactful to our lives,” Resnick 
said.

APPLE HILL STRING QUARTET

THIS WEEK IN HISTORY: STUDENTS DISCUSS MENTALITY BEHIND REVEALING HALLOWEEN 
COSTUMES

October 28, 2011
By Alexandra Mundalen

This weekend, hoards of 

students will roam the streets 
of 
Ann 
Arbor 
dressed 
as 

celebrities, witches, animals 
and pop-culture references, 
while 
wearing 
costumes 

comprised 
of 
tight 
and 

revealing clothing.

Emily 
Richard, 
shift 

manager at American Apparel 
on East Liberty Street, said 
the store fills with shoppers 
searching 
for 
the 
perfect 

costume in the week leading 
up to Halloween — the store’s 
busiest time of the year. Though 

American Apparel doesn’t offer 
packaged costumes, she said it 
sells enough metallic spandex 
and lacy leotards to meet the 
demand of students trying 
to complete their collegiate 
Halloween ensemble.

Richard said she thinks 

female 
students 
often 
opt 

for more revealing costumes 
because of media influence.

“I think it’s kind of easy to go 

the slutty route because that’s 
how Halloween is marketed 
towards girls,” she said.

LSA freshman Abby Lyng 

and 
Engineering 
freshman 

Jillian Jackson said having 
the perfect costume is a one-

way ticket to the best parties, 
as students often compete for 
recognition for the time and 
money spent on their costumes.

Lyng 
said 
she 
dislikes 

dressing 
up 
in 
revealing 

costumes in the cold weather, 
but said that for her and many 
of her peers, practicality and 
sensibility are forfeited on 
Halloween weekend.

LSA 
sophomore 
Paige 

Lester, a member of F-Word 
— a feminist activist group 
on campus — said at the 
organization’s 
meeting 
last 

night that she thinks females

on 
campus 
should 
be 

entitled 
to 
wear 
whatever 

they please on the holiday. to 
im “I think that girls should 
be able to wear whatever they 
want on Halloween,” Lester 
said. 
Catherine 
Berlucchi, 

attendingmanager of Allure 
Boutique 
on 
East 
Liberty 

Street, said the items that 
transform a run-of-the-mill 
cat costume into a sex kitten 
are still in high demand. The 
store sells garter belts and 
fishnet tights to the demand 
of students specifically before 
Halloween. LSA sophomore 
Gia Tame, another member 
of F-Word, said women often 
dress to impress their male 
peers, but questions if the 

same is true for men. “Girls are 
usually dressing for the guys 
because that’s what

think that they have to do,”
mone said. “But are they 

dressing for the girls?”

LSA senior Matt Mortellaro 

said he thinks students often 
dress up on Halloween with the 
intention of impressing others 
than for their own enjoyment. 
“I reject the idea that we 
dress strictly for ourselves,” 
Mortellaro said. “I’m not sure 
that’s possible.” Though there 
might be a mentality among 
female 
students 
that 
men 

prefer scantily dressed women 
on 
Halloween, 
some 
male 

students believed the contrary. 
LSA freshmen Scott Marlatt 
and Benjamin Schmutzer said 
they would rather approach a 
girl dressed in a creative and 
unique costume at a party, 
rather than a girl dressed 
provocatively. “I think that it’s 
wrong,” Marlatt said. “A lot 
of girls are pressured into it 
because it’s what every other 
girl does ... the nurse costume, 
the sailor - all those things are 
overplayed.”
