Adding author name to 'featured post' sticky

Hi there,

I’m using Resonar theme and on the landing page there is a full-width image for a featured-post which is a sticky post. It has the title of the post on the image. I would like to also add the name of the author. The php code is below, is it possible to add author-name to this code and then post to CSS editor?

/*
<?php
/**
* The default template for displaying content
*
* Used for both single and index/archive/search.
*
* @package Resonar
* @since Resonar 1.0
*/
?>

<article id=”post-<?php the_ID(); ?>” <?php post_class(); ?>>
<?php
if ( has_post_thumbnail() && ! post_password_required() ) :
$featuredimage = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), ‘resonar-large’ );
?>
<div class=”entry-header-background” style=”background-image:url(<?php echo esc_url( $featuredimage[0] ); ?>)”>
<div class=”entry-header-wrapper”>
<header class=”entry-header”>
<div class=”entry-header-inner”>
<div class=”entry-date”>
<?php resonar_entry_date(); ?>
</div>

<?php the_title( sprintf( ‘<h2 class=”entry-title”>‘, esc_url( get_permalink() ) ), ‘</h2>’ ); ?>
</div>
</header>
</div>
</div>
<?php else : ?>
<header class=”entry-header”>
<div class=”entry-header-inner”>
<div class=”entry-date”>
<?php resonar_entry_date(); ?>
</div>

<?php the_title( sprintf( ‘<h2 class=”entry-title”>‘, esc_url( get_permalink() ) ), ‘</h2>’ ); ?>
</div>
</header>
<?php endif; ?>
</article><!– #post-## –>
