    Book Cosmology
AI Thread Summary
The author has independently studied cosmology, quantum field theory, and inflation, compiling their findings into a book format and considering self-publishing. They express uncertainty about the book's value due to their background as a retired engineer and amateur astronomer, seeking advice from the forum. While acknowledging the material may not compete with standard textbooks, they believe it could still benefit others interested in the field. Feedback from a forum member highlights potential inaccuracies and suggests improvements for clarity. Ultimately, the discussion concludes with a note that the forum cannot provide the requested review, leading to the thread's closure.

I have been studying cosmology, quantum field theory, and inflation all by myself, taking notes, solving the equations, and when I write down my work, it looks like a book. I think of self-publishing it; I believe it could be useful to others interested in the field.

However, I am only a retired engineer (and amateur astronomer). And I know no one knowledgeable to tell me what it is worth. So I hesitate...

I would be grateful for any advice. Of course, if someone from this forum wants to have a look at my book, let me know. I have a web page on it http://mbond.free.fr/INFLATIONp/inflation.htm.

The material in that link looks like what it is - a student's notes. It's not going to be able to compete with a standard textbook.

I think, in its current form, it is not suitable for systematic learning yet. It can be useful for some people to compare notes or double check their results.

I am interested in particle and event horizons in the ΛCDM model and spent some time on your Fig. 5.7. I noticed that ‘t = 4.02 Gpc’ probably should be ‘t = 4.02 Gyr’. Also, some of your plot results depend on input parameter values. You might want to specify them in the text.
 
Thank you for looking and for your comments. The web page is removed.
 
I'm afraid we cannot provide the review you demanded. The best we can do has already been said.

Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...
