As a result, in order to reproduce the observed correlation, one needs to assume that there is self-regulation among the imposed parameters 5. Too many parameters (e.g., particle acceleration efficiency and magnetization) do not have a strong constraint but must be specified to evaluate the non-thermal emission. Both the well-studied internal shock model 3 and the more recent magnetic reconnection model 4 lack the ability to make firm predictions about the resulting emission properties, since they invoke non-thermal plasma physics with large uncertainties. So far, no theoretical work has provided a fully consistent explanation for the origin of the Yonetoku relation 1, 2. This result strongly suggests that photospheric emission is the dominant component in the prompt phase of GRBs. Although jet dynamics depend sensitively on luminosity, the correlation holds regardless. Our simulations reproduce the Yonetoku relation as a natural consequence of viewing angle. Here we present three-dimensional hydrodynamical simulations, and post-process radiation transfer calculations, of photospheric emission from a relativistic jet. This Yonetoku relation is the tightest correlation found in the properties of the prompt phase of GRB emission, providing the best diagnostic for the radiation mechanism. One unresolved question is the origin of the tight correlation between the spectral peak energy and peak luminosity discovered in observations. ![]() Despite decades of study, there is still no consensus on their emission mechanism. After sweeping your phone in the directions as instructed a few moments of processing, stitching, and AI goodness gives you a nice traditional panoramic image unlike to 360 version I fiddled with earlier using the photosphere mode.Long duration gamma-ray bursts (GRBs), the brightest events since the Big Bang itself, are believed to originate in an ultra-relativistic jet breaking out from a massive stellar envelope. It’s best to keep things steady and straight but I have found it to be quite forgiving when taking horizontal or vertical panoramic images. Use the on-screen grid as a guide as well and pretty soon, taking cool panoramas will be second nature. Again, nothing really new here on the UI side, you choose the mode then follow the onscreen prompts and arrows to take your panoramic image by slowly sweeping your phone in the direction of the arrows while keeping things framed up nicely. Lastly, another feature standard to any decent smartphone purchased in the last decade but made better by the Pixel 6 is panoramic photos. “Jookie Jam” (Mammillaria elongata, the gold lace cactus or ladyfinger cactus) □□ /rWv15vaED6 “Good Gyal” (Pilea cadierei, the aluminium plant or watermelon pilea) □□□□ It even helped me properly identify the two newest plant babies I adopted and hope not to lose due to my poor plant tending skills. I have spent a lot of time pointing my phones at trees and also everyday objects and the recognition hits more time than it misses. Whip out your phone fire up Lens and just point the camera at the tree and Google’s neural network will quickly do the rest. Say you are out and about and you see something you want to learn more about like a sign, or a famous building, or in my case a tree. Next, let’s check out the Google lens a kind of image recognition and searching technology that is available as a standalone app but comes built into the Pixel 6. More on : Amazon Echo Flex - thoughts on smart speakers After the pictures are taken it only takes a few moments for the 360 image to be ready – not long ago this took much longer, was far less user-friendly, and often failed to stitch together seamlessly. ![]() I tested it out on the grounds of a shrine. It works by having you take multiple photos in a circle around you then stitching them together, but instead of the traditional flat panorama image, you can navigate the image in a 360-degree space – very cool for scenic locations. You access it by opening your camera app and going to modes then selecting it. None of these photo features are unique to the Pixel 6 in any way but work great due to the improved AI powers of the Pixel 6 and the work Google has been doing.įirst up are Photo Spheres which are 360 panoramic images. I made a post and a video about my thoughts on the Pixel 6 after a week but I also wanted to explore some more of the camera features, mainly 360 Photo Spheres, Google Lens and Panorama. I have been having a lot of fun fiddling with the Pixel 6, especially the camera.
