The two scientific ways we can improve our photos of event horizons



<div _ngcontent-c14 = "" innerhtml = "

Most-earned black praise of all, like in one's movie Interstellar, forgets that a pastor event is horizontally free enough for a very specific class of rotating black holes. The first image of an Event Horizon Telescope was made at least lower resolution than this visualization, but we can do it in & # 39; Find out more details in the future.

To solve each astronomical object, you must decide again on the resolutive size of your & nbsp; goal to control.

The rogue material is stored on a black hole, taken up or expelled, and can re-form rapidly into planetarium massages. Get it & # 39; hole & # 39; in the center of this gas, the number of well hoses must fit over your telescope gauge to fit a sharper solution than the apparent size of "hole" itself.

The biggest black holes, such as from & # 39; the earth viewed, have & nbsp; events horizons only & nbsp; tens of microarcseconds (μas) in angels size.

The first horizontal image of the Horizon Telescope executes resolutions of 22.5 microseconds, making the array the possible horizon of & # 39; to limit a black hole in the middle of M87. A single-dish telescope would have to be 12,000 km in diameter in order to make this very sharp.

A resolution of telescope, in the meantime, is determined by how many lanterns of light fit through its physical diameter.

This compiled image of a region of the famous universe (top left) uses optical (top right) and non-infrared (lower left) data of Hubble, along with far-infrared (lower right) data of Spitzer. The Spitzer-spatial telescope is almost as large as Hubble: more than a third of its diameter, but the lanyards that try to do so are so much longer that its resolution is still less. The number of line lengths that does not match the diameter of the primary mirror is what determines the resolution.

We can & nbsp; earn this limit by using an array of telescopes, the use of the technique of very long-baseline interferometry.

The Atacama Large Millimeter / Sub-Millimeter Array, such as photographing with the Magellanic Clouds. A large number of kitchens close together, as part of ALMA, helps many of the nasty details in & # 39; Retrieving lower resolutions, while a smaller number of more lavatory patents explain the details of the most visible locations. ALMA's add-on to the Event Horizon Telescope was made to make an image of the event horizontal.

By resolving and calibrating each participating telescope, resolution resolves, & nbsp; a breakthrough of a separate telescope's diameter with the maximum distance of the array.

Only the Antarctic telescope was not able to create M87 image, to see it on the wrong part of the earth that the central galaxy would ever see. Each one of these locations is equipped with an atomic clock, including pieces of equipment.

At & nbsp; the Event Horizon Telescope's maximum baseline & nbsp; and wavelength capabilities, it & nbsp; wool & nbsp; gaining ranges of ~ 15 & nbsp; μas: a 33% improvement on the first observations.

All of these images of the same purpose were taken with the same telescope (Hubble), but were generated wells as you go from left to right. That's why they have higher, sharper resolutions on & # 39; link. The left images also have a higher frequency than a shorter wavelength; In our radiopart of the spectrum, we often talk about frequency rather than longevity, for most historical reasons.

Currently limited & nbsp;345 GHz, we can fight & nbsp; for higher radio frequencies like 1-time-1.6 tz, progress & nbsp; our resolution only ~ 3 to 5 & nbsp; μas.

This picture shows that the radio telescope of the Spektr-R (RadioAstron) space is at the integration and test complex of Launch Pad No.31 at the Baikonur Space Center. This is today our largest, most powerful telescope in all space. If we need a telescope array such as the equipment to deal with the rest of the Event Horizon Telescope, we can expand our baseline to hundreds of thousands of miles.

But the biggest increase would come from the presentation of our radio telescope array in space.

Show the Earth-Moon distances as scale, relative to the size of the earth and month. This is what the month seems to be about 60 earth radians: the first & # 39; astronomical & # 39; distance that was previously determined, over 2000 years ago. Note that the longer the baseline the Earth-Moon distance compares to just the diameter of the Earth.

From their atomic clocks and fast data traditions, our baseline can expand to the size of a month of & # 39; month.

As a material is defeated by a black hole, it will abolish and radiate in various lusts. While our first image of a black left horsehorse came from observing at a frequency of 230 GHz and with a baseline of about 12,000 km, higher frequencies and longer baselines could potentially result in images as sharp as shown above.

NASA / JPL-Caltech

With both frequencies and baseline improvements we can reach ~ 0.05 & nbsp; μas & nbsp; resolution: 440 times then sharpen our first event horizon image.

In April of 2017, all 8 of the telescope / telescope arrays connected to the Event Horizon Telescope were to Messier 87. This is what a supermassive black hole is, where & # 39; it's clear the event horizontally is. Only via VLBI can we make the resolution for creating an image, but it does exist to improve once & nbsp; hundreds of times as sharp.

To solve any astronomical object, you need to offer resolutions that are superior to the apparent size of your goal.

By adjusting and calibrating each participating telescope, the resolution scarifies, making a cellular telescope through the maximum distance of the array.
