Not sure if this was addressed to me, but in case it was: I actually did my Ph.D. thesis on double-barred galaxies, and have continued to work on and off on barred galaxies over the years; here's a partial list of paper's I (Peter Erwin) have authored or co-authored on the subject: https://ui.adsabs.harvard.edu/search/fq=%7B!type%3Daqp%20v%3D%24fq_database%7D&fq=%7B!type%3Daqp%20v%3D%24fq_property%7D&fq_database=database%3A%20astronomy&fq_property=property%3A%20refereed&q=author%3A(%22erwin%2C%20p%22)%20abs%3A(barred)&sort=date%20desc%2C%20bibcode%20desc&p_=0 https://ui.adsabs.harvard.edu/search/fq=%7B!type%3Daqp%20v%3...
