Guidance with publishing a conferences paper alone
I think it's almost impossible, if not truly so, to do your first publications without assistance (assuming those publications are to be in legitimate, reputable venues). You say your only option is to publish by yourself without guidance; my advice is strongly to say that path is not likely to be fruitful and suggest that you reconsider your other options.

I don't know what you have to do or can do to get an advisor at this point, but do that. If you were an undergraduate looking for a graduate program, I would strongly advise that you choose a program that shares your interest in doing research, and make sure you will be supported in that research. Since that choice is in the past, your options are limited, and you'll have to consider what makes most sense for you...

It might mean working through your program's staff to help connect you with someone if people aren't responding on their own.

It might mean reaching out to professors who teach courses you take and asking them for advice, if not on your research directly then on finding an advisor.

It might mean rethinking the specificity of your research interests and instead working on problems someone else finds interesting. Only tenured professors have the most opportunity to choose their own problems.

It might mean finding a collaborator outside your institution.

It might mean changing programs.

Things in most places are pretty messed up right now and these do not qualify as ordinary times, especially in NYC; your best options might include some patience and waiting for things to return to a more stable setting.



Too many possibilities and too many unknowns/factors specific to you and your current institution to give any specific answer, but the process of research, not just the contents, are difficult enough with help. This is not a good time in your career to venture out alone prematurely.
