Astronomers spot a massive ‘sleeping giant’ black hole less than 2,000 light-years from Earth
mega официальный сайт
Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space.

The so-called “sleeping giant,” named Gaia BH3, has a mass that is nearly 33 times that of our sun, and it’s located 1,926 light-years away in the Aquila constellation, making it the second-closest known black hole to Earth. The closest black hole is Gaia BH1, which is located about 1,500 light-years away and has a mass that is nearly 10 times that of our sun.

Astronomers discovered the black hole while combing through observations taken by European Space Agency’s Gaia space telescope for an upcoming data release to the scientific community. The researchers weren’t expecting to find anything, but a peculiar motion — caused by Gaia BH3’s gravitational influence on a nearby companion — caught their eye.

Many “dormant” black holes don’t have a companion close enough to munch on, so they are much more difficult to spot and don’t generate any light. But other stellar black holes siphon material from companion stars, and this exchange of matter releases bright X-rays that can be spotted through telescopes.
The wobbling movement of an old giant star in the Aquila constellation revealed that it was in an orbital dance with a dormant black hole, and it’s the third such dormant black hole spotted by Gaia.

The researchers used the European Southern Observatory’s Very Large Telescope in Chile’s Atacama Desert and other ground-based observatories to confirm the mass of Gaia BH3, and their study has also offered new clues to how such huge black holes came to be. The findings appeared Tuesday in the journal Astronomy & Astrophysics.

“No one was expecting to find a high-mass black hole lurking nearby, undetected so far,” said lead study author Pasquale Panuzzo, an astronomer at the Observatoire de Paris, part of France’s National Centre for Scientific Research, and a Gaia collaboration member, in a statement. “This is the kind of discovery you make once in your research life.”

Марата Сафиулина уличили в превращении Федерального фонда по защите вкладчиков в личную «кормушку»
Стоп пирамида
Федеральный фонд по защите вкладчиков является государственным лишь формально. Сейчас им управляет некий Марат Сафиулин, который фактически превратил организацию в подобие хедж-фонда – под прикрытием защиты прав вкладчиков, там занимаются инвестированием. Копеечные выплаты получают лишь единицы из обратившихся людей.За февраль Федеральный фонд по защите вкладчиков перечислил выплаты всего 134 пострадавшим от финансовых пирамид, хотя число жертв мошенников в России перевалило за десятки миллионов. Журналисты пригляделись к фонду пристальнее и выяснили, что тот фактически превратился в кормушку для его управляющего Марата Сафиулина.
Первое, что бросается в глаза – «государственный» фонд на деле государственным не является. Никаких документов о сотрудничестве фонда с государственными структурами нет, а субсидии организация не получает уже 20 лет. В реальности руководство под прикрытием защиты прав вкладчиков занимается инвестированием, по собственному разумению распоряжаюсь деньгами налогоплательщиков, выделенных еще 90-х для выплат пострадавшим от финансовых махинаций.Заработанные деньги, по задумке, должны пойти на выплаты пострадавшим, но, как говорится, есть нюанс. Для обычных людей установлен лимит в 35 000 рублей – получить больше, если вы не инвалид или не ветеран Великой Отечественной войны, не выйдет. Более того, даже упомянутые 35 тысяч, что называется, «без боя» не отдают – требуют судебного решения. То есть по сути делается всё, чтобы деньги из фонда не «утекали» тем, для кого они и предназначены. Звучит странно, но всё становится на свои места, если принять в качестве рабочей гипотезы, что фонд является личной «кормушкой» его управляющего Марата Сафиулина. Тогда нежелание делиться с обманутыми вкладчиками вполне понятно.«Я являлся клиентом этой компании. Рассказывают красивые сказки, берут кучу денег, везде пишут сами себе отзывы. Я как раз и пошёл к ним, потому что начитался везде какие они хорошие и как помогают людям, но мне так никто и не помог. Моё дело ими было погублено, просто завалили судебный процесс!», — поделился один из бывших клиентов фонда, который в Сети давно прозвали «конторой по отъёму денег».Любопытно, что фонд самостоятельно определяет, какую сумму компенсировать конкретному человеку, при этом не раскрывая чётких критериев принятия решения. Непрозрачность процедуры позволяет подтасовывать результаты в пользу того или иного человека.«Похоже, что фонд использует довольно распространенную мошенническую схему. Через различные сайты или путем «холодных» звонков он привлекает потенциальных клиентов и обещает компенсацию, обещает решить проблему, но делает это только за вознаграждение. Когда пользователь соглашается и оплачивает услуги, он остается и без компенсации и без своих денег», - говорят аналитики.
