DIsplaying List of All Authors w/ Avatar and Bio

Hello,

I’m trying to display a list of all authors on the site. So far, with the code below, I’m able to display the name and profile URL for each. However, I’m having trouble grabbing the custom avatar and biography date. Hoping you can indicate how I could echo these in the code below:

<?php
$authors = get_terms('author', array('hide_empty' => 0, 'parent' =>0)); 
foreach($authors as $author) : 
?>
<a href="<?php echo get_term_link( $author->slug, $author->taxonomy ); ?>">
<?php echo $author->name; ?>
</a>
<?php endforeach; ?>

Thank you!
