Can you help me find out what this guy's name is?

Question

I'm a publisher. Yesterday I received an email from someone who wanted me to publish his book. However, he refused to send it to me unless I figured out his name. I sent back an email with the answer 'Rumplestiltskin', but he said no. Instead, he sent me this:

bar.gjb.gjb.gjb.gjb/gjb.gjb.gjb.gjb.bar|bar.bar.bar.bar.bar|bar.bar.bar.bar.bar ^
bar.gjb.gjb.gjb.gjb|bar.bar.gjb.gjb.gjb/bar.bar.bar.bar.bar ^
bar.bar.bar.bar.bar|bar.gjb.gjb.gjb.gjb/bar.bar.gjb.gjb.gjb ^
bar.bar.bar.bar.bar|bar.gjb.gjb.gjb.gjb/bar.bar.gjb.gjb.gjb <>
bar.bar.bar.bar.bar|bar.gjb.gjb.gjb.gjb/bar.bar.bar.gjb.gjb ^
bar.bar.bar.bar.bar|bar.bar.bar.bar.bar <>
bar.gjb.gjb.gjb.gjb|gjb.gjb.gjb.gjb.bar|bar.bar.gjb.gjb.gjb/bar.bar.bar.bar.bar ^
bar.bar.bar.bar.bar|bar.gjb.gjb.gjb.gjb/gjb.gjb.gjb.gjb.bar ^
bar.gjb.gjb.gjb.gjb|bar.bar.gjb.gjb.gjb/bar.bar.bar.bar.bar|bar.bar.bar.gjb.gjb|gjb.gjb.gjb.bar.bar ^
bar.bar.bar.bar.bar|bar.gjb.gjb.gjb.gjb/bar.bar.bar.gjb.gjb ^
bar.gjb.gjb.gjb.gjb|bar.bar.gjb.gjb.gjb/bar.bar.bar.bar.bar ^
bar.bar.bar.bar.bar|bar.bar.bar.bar.bar ^
bar.bar.bar.bar.bar|bar.gjb.gjb.gjb.gjb/bar.bar.gjb.gjb.gjb

Can you help me figure out what Mr. Bar Gjb's real name is?

Hint 1:

13. Decaying.

Hint 2:

What's an anagram of here come dots?

Answer 1

The first hint...

... alludes to rot13 encoding, which converts bar and gjb to one and two. _{Confirmed by OP}

The second hint...

... refers to Morse code. _{Confirmed by OP}

The bar/gjb sequences are...

... organised in groups of five. In Morse code, the numerals all have five signals. Taking bar/one as dit and gjb/two as dah, the message reads:

1 / 9 | 5 | 5 ^
1 | 2 / 5 ^
5 | 1 / 2 ^
5 | 1 / 2 <>
5 | 1 / 3 ^
5 | 5 <>
1 | 9 | 2 / 5 ^
5 | 1 / 9 ^
1 | 2 / 5 | 3 | 8 ^
5 | 1 / 3 ^
1 | 2 / 5 ^
5 | 5 ^
5 | 1 / 2
_{Confirmed by OP}

Each line...

... represents a letter. The caret denotes the end of a letter, the diamond denotes the end of a word. _{Confirmed by OP}
As @yuzuki observed in a comment, the slash probably means that two adjacent digits are joined into a larger number. After joining the numbers and removing the end markers of the letters, we get:

19 | 5 | 5
1 | 25
5 | 12
5 | 12
5 | 13
5 | 5
1 | 9 | 25
5 | 19
1 | 25 | 3 | 8
5 | 13
1 | 25
5 | 5
5 | 12

The next step is...

... to convert the numbers to letters. The number represents the position of the letter in the alphabet, so 1 is A, 2 is B and so on:

see ay el el / em ee / aiy es aych em ay ee el

These are the letters as they are spelt when read out loud. (Although I'd have used ELL and AITCH.)

The sentence reads:

CALL ME ISHMAEL

which is the famous opening line from Herman Melville's Moby-Dick. So the author's name is Ishmael. (The name could also be Herman Melville, but nobody will know the famous quote if the book hasn't been published.)

Footnote:

I had found the answer without figuring out the second step, where series of numbers are treated as letters. It was enough to treat each individual sequence of numbers, say 5|12, as a letter in a monoalphabetic substitution cipher. Just finding that the caret and diamond are letter and word separators was enough to attack the monoalphabetic cipher.
