![]() Supermassive black holes can be millions or billions of times the mass of our sun. The new blazars, which are dim relative to more typical blazars, have allowed the researchers to test a controversial theory of blazar emissions, informing our understanding of black hole growth and even theories of general relativity and high-energy particle physics.Ī paper describing the blazars and the theory has been accepted for publication in the Astrophysical Journal, and the peer-reviewed accepted version appears online on the preprint server arXiv. More than a hundred blazars - distant and active galaxies with a central supermassive black hole that drives powerful jets - have been newly characterized by Penn State researchers from a catalog of previously unclassified high-energy cosmic emissions.

New findings are always reported by multiple publications, and the fact that a specific link has not been submitted does not mean that this topic is not already being discussed on /r/Physics. Please make sure that a submission on the same topic has not been posted already. ![]() For more information on rules related to these posts, please see this thread here. This will serve to generate on-topic discussion, and separate your post from low-effort spam. If you make an image/video post, you should make a comment in the thread describing the relevant physics, linking relevant literature, any computational methods used, etc. Consider posting to /r/PhysicsJokes, /r/PhysicsGifs, or /r/ScienceImages instead. Off-topic images, videos, or otherwise "zero-content" submissions are not allowed.If in doubt, use the title of the original research. The title of your submission should accurately reflect its contents.We aim to be a welcoming place for both academics and the general public, and as such posts with no basis in the current understanding of physics are not allowed as they might serve to misinform. /r/Physics is a place for the discussion of valid and testable science, not pet theories and speculation presented as fact.Neither asking nor assisting with homework is allowed here.Īlternatively, try Physics Forums instead. Questions that are specific homework problems or calculations should be redirected to /r/AskPhysics or /r/HomeworkHelp. Questions about textbook/resource recommendations should be posted in the weekly Textbook and Resource threads.ĭiscouraged or not allowed Homework problems.Inquiries about studying physics should be posted in our weekly Careers and Education thread.Īlternatively, try more specific subreddits such as /r/AskAcademia, /r/GradSchool, /r/GradAdmissions, and /r/PhysicsStudents. Questions regarding job opportunities and working as a physicist have a dedicated weekly Careers and Education thread and should be posted there.Īdditionally, you can search the subreddit to read dozens of past threads about this issue or check /r/AskAcademia for jobs in academia. Note that these questions are always welcome in /r/AskPhysics and /r/AskScience (subject to subreddit rules). Please check the /r/AskScience FAQ or the Usenet physics FAQ before posting. If you are posting a link to your own website, please familiarise yourself with the global rules on self-promotion.Įncouraged in weekly threads Conceptual and closed-ended questionsĭue to a high volume of such questions, they are consolidated in weekly Physics Questions threads. The lack of quality sources is grounds for removal at moderator discretion. We invite links to all websites, but article and blog post submissions require proper sourcing from the literature or mainstream scientific journalism. ![]() Pre-prints are accepted, but moderators reserve the right to delete any posts that break the rules regarding unscientific content. Links to papers in physics journals (free or otherwise) are welcome.Shorter questions which are more straightforward to answer will get a better response in /r/AskPhysics. Please make an effort to engage the community rather than simply state your views and expect others to validate them. IRC Channel: #physics on chat with us Encouraged submissions Open-ended discussionsĭebates and discussions on all topics related to physics are welcome. Please choose a user flair using the 'edit' option next to your username above. Posts should be pertinent and generate a discussion about physics. The aim of /r/Physics is to build a subreddit frequented by physicists, scientists, and those with a passion for physics. ![]()
