How to use WP_Query to get co-authors and args?

Hi, I’m trying to use WP_Query to get a list of co-authors and pass any arguments allowed. Any help? Thanks!

$args = array(
	'post_type' => 'post',
	'tax_query' => array(
		'relation' => 'AND',
		array(
			'taxonomy' => 'my_post_taxonomy',
			'field' => 'slug',
			'terms' => array( 'my-post-taxonomy' )
		),
		array(
			'taxonomy' => 'author',
			'field' => 'id',
			'terms' => array( 103, 115, 206 ),
			'operator' => ''
		)
	)
);
$query = new WP_Query( $args );

P.S. I know there is a function “coauthors_wp_list_authors” but I need to use WP_Query.
