<*.txt>

What does this mean?

@aList = map {s/\.txt//g; s/_/ /g; $_;} <*.txt>;

I think it means "go to the .txt file and take each line, and remove the ".txt" on each line and replace
_ with a space, then add the result to @aList.

How does the script know where to find *.txt? Is &_ the current line in *.txt?

Here it is broken down:

<*.txt>  -- Get the list of files and directories in the current directory ending in ".txt"

map      -- For each filename (or directory name) in the above list execute the following code and construct a list

s/\.txt//g -- Remove ".txt" from the filename and put the value in the default variable $_

s/_/ /g    -- Replace all _'s with spaces from the default variable $_ and put the value back into $_

$_ -- Add the filename with the above replacements to the list constructed by the map function

@aList=   -- Assign the list created by the map function (of all filenames with .txt and _ replaced) to the variable @aList.
