Rare galaxy with 2 black holes has 1 starved of stars

An astrophysicist has discovered something even rarer than a double-black hole galaxy: a skinny black hole.

The University of Colorado at Boulder's Julie Comerford reported her findings Tuesday at the American Astronomical Society's annual meeting in Kissimmee, Florida.

To date, only 12 galaxies are known to exist with two black holes in their midst, Comerford said. Normally galaxies have a single supermassive black hole at the center, equivalent to 1 million to 1 billion times the mass of our sun.

But in this newly identified galaxy about 1 billion light-years away, one of the two black holes is significantly smaller than the other and apparently starved of stars. Black holes typically are surrounded by stars; this one appears "naked."

Comerford speculates the slim black hole lost mass in the collision of two galaxies that merged into this one —" a crash diet." Or it's a rare example of an intermediate-sized black hole that likely will morph over time into a supermassive monster.

Astronomers have yet to confirm an intermediate-size black hole, which makes Comerford's streamlined target extra tantalizing. Intermediate black holes are 100 to 1 million times the mass of our sun.

Comerford used the Hubble Space Telescope and NASA's Chandra X-ray Observatory in her study. She discovered this latest two-black hole galaxy — her fourth — last year. Finding a potential intermediate-size black hole inside was "an extra bonus," she told reporters.

The first double-black hole galaxy was found in 2003 by accident, according to Comerford. She is trying to systematically uncover more. The findings should shed light on the evolution of black holes.

Virtual Reality technology could rule 2016

 

The HTC Vive, Sony's PlayStation VR, Facebook's Oculus "Rift" and Samsung's "Rink" headset will be seen in the market in the next few months, BBC reported on Saturday.

Virtual reality is a computer-simulated reality (in a device) that replicates, via photos, an environment that simulates a physical presence in places in the real world or an imagined world, allowing the user to interact in that world.

Virtual reality artificially creates sensory experiences which can include sight, hearing, touch and smell.

For example, with a VR device you can climb Mount Everest making your way gingerly across a shaky bridge while trying not to look down into an icy chasm -- all while sitting on a couch in your house.

The devices may be showcased at the International Consumer Electronics Show (CES) that will be held from January 6 to 9 in Las Vegas.

The HTC Vive is seen as the device providing the best VR experience. Its launch, slated for last year, was delayed for some further tweaking.

Sony's PlayStation VR and Facebook's Oculus "Rift" headsets can be seen in the markets in the next few months while Samsung has big plans to unveil its "Rink" at the CES.

Apart from gaming, Virtual Reality technology may prove to be a ground-breaking technology in many areas of life, the report said.

Two psychologists from London, Ashley Conway and Vanessa Ruspoli, developed a system that uses Oculus' Rift headset to treat patients with phobias.

Their company Virtual Exposure Therapy aims to give patients exposure in a virtual world to the thing they fear.

"It is not the real world but a very visceral experience. You get a physiological reaction. It is a really good bridge between not being able to do something and doing it in the real world," Conway explained.

But we will have to wait a little longer for the launch, price and feedback details of the respective devices.

New World Hackers claim responsibility for BBC website attack

 

A day after the cyber-attack (DDOS) on BBC’s website, an “Anti IS” group has claimed responsibility of the hit which took down the entire network of the British broadcaster’s websites for several hours.

On Saturday, a group named New World Hackers claimed the responsibility of the attack in a tweet to BBC technology correspondent Rory Cellar-Jones.

In another tweet to Jones, the group also said: "We are based in the US, but we strive to take down Isis [IS] affiliated websites, also Isis members. We realise sometimes what we do is not always the right choice, but without cyber hackers... who is there to fight off online terrorists? "The reason we really targeted [the] BBC is because we wanted to see our actual server power."

The BBC's online services, including its news website and iPlayer catch-up TV platform, were taken down on Thursday by a large web attack, the British broadcaster reported.

The BBC's sites, which rank only behind Google and Facebook in visitor numbers in Britain, according to Internet analytics firm comScore, were hit from 0700 GMT, with many users receiving an error message rather than content.

The broadcaster itself reported it had been hit by a "distributed denial of service (DDoS)" attack, citing sources within the organization.

DDoS attackers typically target sites by flooding servers with messages from multiple systems so they are unable to respond to legitimate traffic.

Earlier, the BBC press office said it would not confirm or deny it had been hit by an attack.

"We're aware of a technical issue affecting the BBC website and we are working to fix this now," the BBC press office said.

It said at 1145 GMT its sites were back up and operating normally.

Mobile phone subscribers in India exceed one billion

 

New Delhi: India notched up its billionth mobile phone subscriber in October, the country's telecoms regulator said, underscoring the importance of its fast-growing mobile market, the world's second largest after China.    

Mobile phone subscriptions have boomed in India in recent years as aggressive cost-cutting by its 12 hyper-competitive operators has driven down prices, leading to some of the cheapest tariffs in the world.       

The number of mobile subscribers rose by nearly 7 million in October from the previous month to surpass one billion, the Telecom Regulatory Authority of India said Wednesday, hitting a milestone that China reached in 2012.              

"It is a matter of great pride for us. It shows an empowered India and an engaged India and a tech-savvy India," Communications and IT minister Ravi Shankar Prasad told the Times of India newspaper.         

"It will mean more data, more government-to-government connectivity, more broadband," he said.       

The figures do not indicate that India has one billion individual mobile phone users, however, as many people have more than one connection.              

"Dual sim" phones are particularly popular, allowing the country's cost-conscious consumers to use two different mobile plans to get the cheapest rates for local or national calls, for example.       

In poorer Indian states such as Bihar, "teledensity"—the penetration of telephone connections for every hundred people—is as low as 54 percent, with a stark urban-rural divide.        

But it still represents remarkable growth in the market since 2000, when there were just two million mobile subscribers in the country, according to research firm Ipsos.

India is adding 10 to 15 million mobile subscribers every quarter—that's big," Bhasker Canagaradjou, head of business consulting at Ipsos in Mumbai, told AFP.      

"It is the fastest-growing market globally—even China is not growing as fast," he said.      

With more than 200 million Indians mostly in rural areas yet to get their first phone and others rushing to trade up to smartphones, growth is unlikely to slow down dramatically, Canagaradjou said.
